dlls/ntdll/tape.c portability

[Gerald Pfeifer]

The addition of dlls/ntdll/tape.c broke the build on FreeBSD, and I
assume all other non-Linux platforms.

This is the first set of fixes, which address the majority of issues.

Gerald

ChangeLog:
Accept MTCOMP as an alias for MTCOMPRESSION on those systems, having the
former, but not the latter.
Only enable operations supported by the host OS in TAPE_CreatePartition()
and TAPE_Prepare().
Add FreeBSD support to TAPE_GetPosition().
