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.
