Use C11 _Static_assert where available.
OPENSSL_COMPILE_ASSERT implements a static assertion, but the error
message is a little weird because it's a hack around the fact that C,
traditionally, doesn't have static assertions.
C11 now does have _Static_assert (a.k.a. static_assert when one includes
assert.h) so we can use that when provided to get cleaner error
messages.
