unix-ffi/machine: Use libc if librt is not present.

basvd · dpgeorge · commit 42caaf14de35 · 2025-04-10T22:53:46.000+10:00
Newer implementations of libc integrate the functions from librt, for
example glibc since 2.17 and uClibc-ng.  So if the librt.so cannot be
loaded, it can be assumed that libc contains the expected functions.
