Automatically disable GnuTLS fallback 

Disable GnuTLS fallback if sufficient glibc version detected. Previously
GnuTLS fallback was used regardless of getrandom() availability in
glibc. Fix this by automatically disabling it when not needed. This does
not affect the ability to manually disable it unconditionally.
