Fix image creation issue

job_prerelease_obs strips all lines of .ks file. This breaks patches in
%post section and results in non-functional images.

Example: this stripped patch
patch -p1 -d/ <<'EOF'

causes this message in the log:

patch: **** malformed patch at line 6: account include system-auth

and the image doesn't boot to UI because of broken systemd configuration.
