BACKPORT: perf: Copy parent's address filter offsets on clone

Backport: context code is different from upstream.

When a child event is allocated in the inherit_event() path, the VMA
based filter offsets are not copied from the parent, even though the
address space mapping of the new task remains the same, which leads to
no trace for the new task until exec.
