lib: Fix clock_gettime linking problems.
Until glibc 2.17 clock_* calls needed explicit -lrt and hence linking
with -lltp fails on older distributions.
Since we do not want to link whole LTP with -lrt this commit adds simple
internal functions for clock_gettime() and clock_getres() calls to be
used internally in the test library.
