tests: adjust rt_sigpending to older kernels

With linux kernels older than v3.9-rc1, compat rt_sigpending syscall
could fail with EFAULT in cases where on later kernels it succeeds.
Adjust the test to handle both cases properly.

* tests/rt_sigpending.c (iterate): Stop iterations if rt_sigpending
failed with EFAULT.
