syscalls/rt_sigqueueinfo01: rewrote testcase

The previous implementation only tested if the syscall can be called at all. Now it also checks if the correct signal and data is sent and received.

---

Notes:
Kept header file in case of future additions.
Other than that: included all suggestions from v2 of this patch.
+ added solution to avoid 'tst_brk(TFAIL, ...)'
