Define TSVTX in tar.h for older POSIX (bug 16978)

As noted in bug 16978, older POSIX versions include

#define TSVTX    01000   /* Reserved */

in the specified contents of <tar.h>, with only the 2001 edition
introducing the notion of XSI-conditional definitions and conditioning
that definition.  Thus, this macro should be defined for
!__USE_XOPEN2K as well as for __USE_XOPEN, and this patch duly defines
it in that case.  Tested x86_64.
