Use getentropy() when available

When available, use getentropy() in preference to SYS_getrandom or
/dev/urandom. This binding is present in glibc 2.25 and the BSDs.

Check for sys/random.h

The function getentropy() is supported on newer versions of MacOS X,
but requires the include file sys/random.h. Check for that and include
it where getentropy() is used.
