libarchive: Avoid a build failure with OpenSSL 3.0

This is a minimal workaround; a proper fix will come via a future update
from upstream.

libarchive: Request the OpenSSL 1.1 API

OPENSSL_API_COMPAT can be used to specify the OpenSSL API version in
use for the purpose of hiding deprecated interfaces and enabling
the appropriate deprecat

libarchive: Request the OpenSSL 1.1 API

OPENSSL_API_COMPAT can be used to specify the OpenSSL API version in
use for the purpose of hiding deprecated interfaces and enabling
the appropriate deprecation notices.

This change is a NFC while we're still using OpenSSL 1.1.1 but will
avoid deprecation warnings upon the switch to OpenSSL 3.0.

A future update should migrate to use the OpenSSL 3.0 APIs.

libarchive: fix mismatch between library and test configuration

I was investigating libarchive test failures on CheriBSD and it turns out
we get a reproducible SIGBUS for test_archive_m5, etc. Debug

libarchive: fix mismatch between library and test configuration

I was investigating libarchive test failures on CheriBSD and it turns out
we get a reproducible SIGBUS for test_archive_m5, etc. Debugging this shows
that libarchive and the tests disagree when it comes to the definition of
archive_md5_ctx: libarchive assumes it's the OpenSSL type whereas the test
use the libmd type. The latter is not necessarily aligned enough to store
a pointer (16 bytes for CHERI RISC-V), so we were crashing when storing
EVP_MD_CTX* to an 8-byte-aligned archive_md5_ctx.

To avoid problems like this in the future, factor out the common compiler
flags into a Makefile.inc and include that from the tests Makefile.
