[gomp4] Small libgomp testsuite tweaks

[Jakub Jelinek]

Hi!

I've noticed that udr-8.C failed on i686-linux, apparently because i
was uninitialized.  udr-3.c had the same bug, but didn't FAIL because
of that on either x86_64-linux nor i686-linux, and udr-2.c had just
unused variable.

        * testsuite/libgomp.c/udr-2.c (main): Remove unused variable i.
        * testsuite/libgomp.c/udr-3.c (main): Initialize i to 0.
        * testsuite/libgomp.c++/udr-8.C (main): Likewise.
