g_check_setuid: implement using getauxval(AT_SECURE) with glibc
See commit 4c2928a544829 for why checking AT_SECURE is preferable compared
to UID checks as currently done in the fallback case.
getauxval() was added with glibc 2.16
While glibc <2.19 didn't provide a way to differentiate a 0 return value from an error,
passing AT_SECURE should always succeed according to
https://sourceware.org/ml/libc-alpha/2014-07/msg00407.html
I've added an errno check anyway, to be on the safe side.
