Skip the test for sys.stdin.seek(-1) on OSF/1 (Tru64) since it does Bad Things
like cause the interpreter to exit abruptly.  If there's a way to fix this,
it would be good to really fix it.  It could just be the operation of the
std C library and we just aren't supposed to do that.

When the test case is skipped, we print a message so the user can check
for themselves.
