Ignore problems when zipping ccache dir
Some builds are failing with this error:
+ zip -r -q /workspace/artifacts/606/ccache/ccache_dir.lhcb-master-ref.x86_64-centos7-gcc9-dbg.zip .ccache
zip error: Zip file structure invalid (/workspace/artifacts/606/ccache/ccache_dir.lhcb-master-ref.x86_64-centos7-gcc9-dbg.zip)
Build step 'Execute shell' marked build as failure
I do not know what's happening, but a failure to publish the cache file is not a good reason to crash the job.
