src/Makefile: Link clock_gettime(2) with -lrt

Compiling t_open_tmpfiles.c failed on older glibc(before glibc v2.17)
because clock_gettime(2) was not linked with -lrt, as below:
--------------------------------------------------------------------
/home/yangxiao/xfstests/src/t_open_tmpfiles.c:36: undefined reference to `clock_gettime'
--------------------------------------------------------------------

According to clock_gettime(2) manpage, we should link clock_gettime(2)
with -lrt on older glibc.
