[PATCH v2] gitlab-ci.yml: Add oss-fuzz build tests |

From: Alexander Bulekov <alxndr@bu.edu>
This tries to build and run the fuzzers with the same build-script used
by oss-fuzz. This doesn't guarantee that the builds on oss-fuzz will
also succeed, since oss-fuzz provides its own compiler and fuzzer vars,
but it can catch changes that are not compatible with the the
./scripts/oss-fuzz/build.sh script.
The strange way of finding fuzzer binaries stems from the method used by
oss-fuzz:

[thuth: Tweak the "script" to make it work, exclude slirp test, etc.]

Note: Needs Alexander's "fuzz: Fix leak when assembling datadir path
string" patch applied first, otherwise it fails due to the leak.
