[flac] Simplify build script (#9773) 

A number of fuzzer names to be copied is removed from the build script.
The naming of various files in FLACs oss-fuzz directory has been changed
so all files that belong in $OUT have the same prefix.

Also, some defaults have changed because of this ticket:
https://github.com/xiph/flac/issues/546 Other projects relying on
libFLAC being fuzzed can now rely on default settings.
