Philip Withnall e66277943d fuzzing: Add copyright/licensing headers to fuzzing files
The files have only been touched by a subset of three people: pdknsk,
Philip Withnall, and Marc-André Lureau. Their copyrights are assigned to
pdknsk, Endless OS Foundation and Red Hat.

The default license for GLib at the time of writing these files was (and
still is) LGPL-2.1-or-later.

`driver.c` came from LLVM and is under a different license:
https://github.com/llvm/llvm-project/blob/main/compiler-rt/lib/fuzzer/standalone/StandaloneFuzzTargetMain.c.
That doesn’t affect the license of GLib overall, since it’s only used
for testing during development.
