Heiko Carstens 36773797e9 s390/uprobes: implement arch_uretprobe_is_alive() 
commit 783c3b53b9506db3e05daacfe34e0287eebb09d8 upstream.

Implement s390 specific arch_uretprobe_is_alive() to avoid SIGSEGVs
observed with uretprobes in combination with setjmp/longjmp.

See commit 2dea1d9c38e4 ("powerpc/uprobes: Implement
arch_uretprobe_is_alive()") for more details.

With this implemented all test cases referenced in the above commit
pass.
