Subject: [PATCH 1/2] perf symbols: Set dso->kernel when handling the fake vmlinux MMAP event

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

Because it may be possible that there was no buildid section, where we
would set this to 1.

Found while analysing a perf.data file collected on an ARM machine where
an explicitely specified vmlinux was being disregarded.
