fuzz: avoid building twice, when running on gitlab

Browse Source 
On oss-fuzz, we build twice, to put together a build that is portable to
the runner containers. On gitlab ci, this is wasteful and contributes to
timeouts on the build-oss-fuzz job. Avoid building twice on gitlab, at
the remote cost of potentially missing some cases that break oss-fuzz
builds.
