perf maps: Remove rb_node from struct map
struct map is reference counted, having it also be a node in an
red-black tree complicates the reference counting. Switch to having a
map_rb_node which is a red-block tree node but points at the reference
counted struct map. This reference is responsible for a single reference
count.
Committer notes:
Fixed up tools/perf/util/unwind-libunwind-local.c to use map_rb_node as
well.
