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

Alexander Hansen Færøyrequested to merge
ahf/tor:ahf/40683 into main

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: #40683 (closed).
