s390/stacktrace: Merge perf_callchain_user() and arch_stack_walk_user()
The two functions perf_callchain_user() and arch_stack_walk_user() are
nearly identical. Reduce code duplication and add a common helper which can
be called by both functions.
Fixes: aa44433ac4ee ("s390: add USER_STACKTRACE support")
