kbuild: uapi: drop dependency on CC_CAN_LINK
The header tests try to compile each header. Some UAPI headers depend on
libc headers so they need a full userspace toolchain to build. This
dependency is expressed in kconfig as a dependency on CC_CAN_LINK.
Many kernel builds do not satisfy CC_CAN_LINK as they only use a
minimal kernel (cross-) compiler. In those configurations the UAPI
headers are not tested at all.
However most UAPI headers do not even depend on any libc headers,
and such dependencies are undesired in any case. Also the static
analysis performed by headers_check.pl does not need CC_CAN_LINK.
Drop the hard dependency on CC_CAN_LINK and instead skip the affected
compilation step for exactly those headers which require libc.

kbuild: uapi: Drop types.h check from headers_check.pl
Since commit d6fc9fcbaa65 ("kbuild: compile-test exported headers to
ensure they are self-contained"), the UAPI headers are compile tested
standalone with the compiler. This compile testing will catch a missing
include of types.h, making the types.h checking in headers_check.pl
originally added in commit 483b41218fa9 ("kbuild: add checks for include
of linux/types in userspace headers") obsolete.
