Building the rseq selftests against musl libc fails because musl's
<features.h> does not provide the glibc-specific __GNUC_PREREQ macro:
error: missing binary operator before token '('
Replace __GNUC_PREREQ(11, 1) with an equivalent check using __GNUC__
and __GNUC_MINOR__ directly. This pattern is portable across all C
library implementations and is already used elsewhere in the tools/
tree (e.g., tools/include/linux/string.h).
This also allows removing the #include <features.h>, which was only
needed for __GNUC_PREREQ.
