[esock] Replace usage of clock_gettime(CLOCK_REALTIME, ...)

The usage of the function clock_gettime(CLOCK_REALTIME, ...)
has been replaced with enif_monotonic_time(ERL_NIF_USEC) and
enif_time_offset(ERL_NIF_USEC). For now its if-def'ed so that
we still *can* use clock_gettime, but for the momemnt its
not used even if its available.
