build: add check for clock_gettime() in librt
zuctest is another clock_gettime() user that fails to link against librt when
necessary.
Instead of adding another -lrt LDADD entry i've opted for the saner way and
converted the check to a configure test that will set CLOCK_GETTIME_LIBS
appropiately and replaced all instances of -lrt with it.
Built-tested against old and new glibc.
