[packman] Modification in workers build script

[Cristian Morales Vega]

build-compare fails with xine-lib x86-64 packages with:

/var/run/obs/worker/1/build/build: line 2025:
/srv/obs/workers/root_1/.build/.same_result_marker: No such file or
directory

The problem seems to be fixed in these commits:
http://gitorious.org/opensuse/build/commit/df2d0f11d7e6f9f09f4eea39c1b093c25e14a9b7
http://gitorious.org/opensuse/build/commit/8a24d94fdce0484889c7e3f7d253fc9b3ee85074

Could they be applied in the workers build scripts?
