[LTP] [PATCH v1] Replace ltp_syscall with tst_syscall

So far we've done cleanup as whole test one by one.
Sure, why not solving one issue once.

Generally LGTM. I'd just appreciate if tst_test.h didn't have to be loaded at
first, but that's a minor issue.

also with these whole tree patches it's a problem that it either breaks some of
other patches (they will not be applicable) or this patch will not be applicable
(if not applied soon after the release).

Kind regards,
Petr
