[PATCH v2 20/20] scripts/xeno-config: Allow disabling the y2038 / time64_t support

xeno-config got a new cmdline option --disable-y2038 that will disable
the time64_t or (year 2038) support inside the application that is
being build against libcobalt.

libcobalt provides both interfaces, so for native time_t and for
time64_t at the same time. By default, the time64_t based interfaces
will be used. If an application does really want to go back to native
time_t --disable-y2038 has to be specified before the --cflags option.

The new parameter is only useful for (old) 32 bit applications.
