[OE-core] [PATCH 1/1] classes/buildhistory: do not save old packagehistory files by default

[Paul Eggleton]

Disable storing package history as version named files unless
BUILDHISTORY_KEEP_VERSIONS is set to 1; otherwise the adds of these
files that duplicate what is already in git anyway is just noise in the
git log.
