mozjs 17.0.0: fix aarch64 and 64k page builds, generic cleanups

* Mozjs17 has problems with 64k page sizes (powerpc64, aarch64 and probably others) and lacks support for aarch64. Patches were lifted from the fedora src rpm and rediffed.

* Regenerate configure with autoconf-2.13 to make the fixes mentioned above take effect.

* Provide proper config.guess and config.sub files

* Explicitly disable static builds and regroup configure options.

* Also clean out the patches/ dir present in the tarball to avoid conflicts with the OE patcher.
