Subject: [PATCH] use correct dir for creation of icecream env
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

/var/run might point to the absolute path /run. Thus any commands
referencing $BUILD_ROOT/var/run are actually using the hosts /run
directory, whereas the "cd" tries to change to the nonexisting
/run/icecream directory and fails.

This is a cherry-pick from upstream:
https://github.com/openSUSE/obs-build/commit/21359a6ebcbacdb1754a7c4339a7cca7e496e52f
