wayland: use glib function for fetching timestamp

Browse Source 
The code currently implements a function, get_time, that
fetches a timestamp.  That duplicates code already in glib,
and the glib implementation is better, anyway, since it doesn't
skew backward when the system clock is changed.

This commit changes the code to use g_get_monotonic_time and
drop the get_time function.
