Kill off OSMAJORVERSION and OSMINORVERSION defines/cpp flags

This has meant very little for a long time as configure.ac just
hardcoded these values depending on the current OS versions at the
time.

The only place where this is really 'needed' is XlationSvc.c in DtSvc
so that differences between locale specifications on various versions
of an OS can be accounted for. So for now, we just define those when
building DtSvc.

We could probably safely remove them as well with an update to the
Xlate locale DB to remove ancient cruft we don't care about anymore.

For various other modules, like dtlogin, dtsession, etc we just use
the code that was already being used due to the hardcoded values we've
had for the last 10-ish years.
