Subject: [PATCH] fix default feature profile in tar.h

commit d93c0740d86aaf7043e79b942a6c0b3f576af4c8 added use of feature
test macros without including features.h, causing a definition that
should be exposed in the default profile, TSVTX, to appear only when
_XOPEN_SOURCE or higher is explicitly defined.
