Strip "__.SYMDEF*" before re-archiving in combine_libs on macOS and iOS.

This patch changes how combine_libs works on Darwin like platforms to
make sure we don't include any `__.SYMDEF` and `__.SYMDEF SORTED`
symbols on the archive before we repack and run ${RANLIB} on the
archive.

See: tpo/core/tor#40683.
