[OE-core] [PATCH 6/8] classes/buildhistory: handle additional files at recipe level

[Paul Eggleton]

Avoid an error when attempting to remove previous data if it's not a
subdirectory - we were assuming that anything that wasn't named "latest"
or "latest_srcrev" had to be a directory. This makes it possible to have
a buildhistory_emit_pkghistory_append which writes additional files at
the recipe level.
