tools/oss-fuzz: add clang library dir using -L

Browse Source 
I have no idea why clang doesn't do this on its own, and why clang
makes it so hard to query this path (-dumpversion returns something
unrelated...).

I know this is an ugly hack, but this is a very specialized script,
so it should be OK to make it a bit hacky.

Tested to work on Fedora (27) and Debian (unstable).

Fixes #8428.
