[OE-core] [PATCH 39/61] distcc: fix initscript can not stop distcc daemon correctly

[Armin Kuster]

From: Hongxu Jia <hongxu.jia at windriver.com>

The distcc's initscript has used option '--pid-file' to save daemon
process id, but it didn't to create that file, that caused start/stop
distcc daemon failed.

We refer what Ubuntu 14.04 did, create pid file before start and
delete it after stop
