certs: Add support for using elliptic curve keys for signing modules

Add support for using elliptic curve keys for signing modules. It uses
a NIST P384 (secp384r1) key if the user chooses an elliptic curve key
and will have ECDSA support built into the kernel.

Note: A developer choosing an ECDSA key for signing modules should still
delete the signing key (rm certs/signing_key.*) when building an older
version of a kernel that only supports RSA keys. Unless kbuild automati-
cally detects and generates a new kernel module key, ECDSA-signed kernel
modules will fail signature verification.

certs: Trigger creation of RSA module signing key if it's not an RSA key

Address a kbuild issue where a developer created an ECDSA key for signing

secting the kernel for example, that does not support ECDSA keys.

If openssl is installed, trigger the creation of an RSA module signing
key if it is not an RSA key.

"Here's a set of patches from Eric Snowberg[1] that add support for
EFI_CERT_X509_GUID entries in the dbx and mokx UEFI tables (such
entries cause matching certificates to be rejected).

These are currently ignored and only the hash entries are made use of.

Additionally Eric included his patches to allow such certificates to
be preloaded.

These patches deal with CVE-2020-26541.

To quote Eric:
'This is the fifth patch series for adding support for
EFI_CERT_X509_GUID entries [2]. It has been expanded to not only
include dbx entries but also entries in the mokx. Additionally
my series to preload these certificate [3] has also been
included'"

Merge branch 'ima-module-signing-v4' into next-integrity

From the series cover letter:

Kernel modules are currently only signed when CONFIG_MODULE_SIG is enabled.
The kernel module signing key is a self-signed CA only loaded onto the
.builtin_trusted_key keyring. On secure boot enabled systems with an arch
specific IMA policy enabled, but without MODULE_SIG enabled, kernel modules
are not signed, nor is the kernel module signing public key loaded onto the
IMA keyring.

In order to load the the kernel module signing key onto the IMA trusted
keyring ('.ima'), the certificate needs to be signed by a CA key either on
the builtin or secondary keyrings. The original version of this patch set
created and loaded a kernel-CA key onto the builtin keyring. The kernel-CA
key signed the kernel module signing key, allowing it to be loaded onto the
IMA trusted keyring.

However, missing from this version was support for the kernel-CA to sign the
hardware token certificate. Adding that support would add additional
complexity.

Since the kernel module signing key is embedded into the Linux kernel at
build time, instead of creating and loading a kernel-CA onto the builtin
trusted keyring, this version makes an exception and allows the
self-signed kernel module signing key to be loaded directly onto the
trusted IMA keyring.
