Doxygen: Don't strip JavaScript anymore

The stripping method worked well with Doxygen 1.8 and 1.9 but
it doesn't work with Doxygen 1.10 anymore. Since we won't ship
pre-generated liblzma API docs anymore, the extra bloat and
extra license info of the JavaScript files won't affect the
upstream source package anymore.
