perf kmem: Do not ignore mmap events
The perf kmem command didn't process mmap events for some unknown reason
and it instead gets symbol info from a running kernel. This is
problematic if perf kmem record was run on a different kernel.
This patch adds the mmap event handlers and reverts the commit
e727ca73f85d ("perf kmem: Resolve kernel symbols again").
