checklicenses: Remove whitelisted licenses not being used

Removed a few licenses we shouldn't use (Apache v2, BSD 4-clause) and
removed many others not currently being used. (Add on a need-to basis).

Added GPLv3+ with Bison exception to licensecheck.pl.

Also removed some crud to work around bugs for older licensecheck.pl versions.

The original list came from the chromium project, which has a BSD-like license,
and many more licenses in use, not all of them vetted for GPLv2+ compatibility.
