[LTP] [PATCH] setfsuid01.c: Rewrite using new LTP API

[LTP] [PATCH] setfsuid01.c: Rewrite using new LTP API

[Avinesh Kumar]

Rewrite with new API and add test to verify that filesystem user ID was
correctly updated by calling setfsuid(-1) which will always fail but
will return the previous filesystem user ID.
