perf unwind: Call unwind__prepare_access for forked thread
Currently we call unwind__prepare_access for map event. In case we
report fork event the thread inherits its parent's maps and
unwind__prepare_access is never called for the thread.
This causes unwind__get_entries seeing uninitialized
unwind_libunwind_ops and thus returning no callchain.
Adding unwind__prepare_access calls for fork even processing.
