Restore failing when CVE scanner finds a vulnerability

During the migration to GitHub Actions in #160 this functionality
was mistakenly and overzealously removed. Since PHP 8 and
Alpine 3.13 are out and #166 has been filed, currently with a CVE
for musl in it, this check should have failed as it is our goal
to ship images without known CVE's in it. On my own PHP images
the CVE checking fails and as such I was surprised that #166
didn't have any failures. Up on checking the CI logs it showed
the musl CVE but the step didn't fail.

This commit restores the original functionality and will make the
CI once again fail when it finds a CVE in one of the images.
