[PATCH 18/52] perf map: Shorten map_groups__find_by_name() signature

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Another step in the road to elliminate the MAP_{FUNCTION,VARIABLE}
separation, reducing the exposure to these details in the tools using
the symbol APIs.
