tests: Skip "build/ALL/gem5.opt" build test

This commit,
https://gem5-review.googlesource.com/c/public/gem5/+/57509, added
'constants.all_compiled_tag' to test the "build/ALL/gem5.opt" target
once incorporated. However, the test_build.py tests automatically parse
these tags to generate build tests. As such the nightly tests fail
due to trying to build a target which has not yet been added to the
project: https://jenkins.gem5.org/job/nightly/183

This patch skips this build. It may be reverted once
"build/ALL/gem5.opt" is available.
