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
e727ca73f8 ("perf kmem: Resolve kernel symbols again").
