[PULL 05/12] gitlab-ci/build-oss-fuzz: print FAILED marker in case the test failed and run all tests

[Thomas Huth <thuth@redhat.com>]

From: Michael Tokarev <mjt@tls.msk.ru>

currently, if an oss-fuzz fails, the script does just `exit 1`
without any additional output, and looking at the build log in
the gitlab ci it is not clear what actually failed, without
looking at build-oss-fuzz script and seeing this `exit 1`.

Print easily recognizable error message about test failure, so
it becomes obvious what exactly has failed.

While at it, continue running other tests even in case of
failure, and exit non-zero if at least one test failed.
