[PATCH] get_maintainer: apply all .get_maintainer.ignore files

[Jeffy Chen <jeffy.chen@rock-chips.com>]

Currently we are searching "./:$ENV{HOME}/:.scripts/" for ignore file,
but would always get "./.get_maintainer.ignore" only.

This patch applies all .get_maintainer.ignore, so it would be easier to
add ignore list locally.
