Stop invoking undefined behaviour by using tor_free() on an unaligned pointer
... in get_interface_addresses_ioctl().
This pointer alignment issue exists on x86_64 macOS, but is unlikely to exist
elsewhere. (i386 macOS only requires 4-byte alignment, and other OSs have
8-byte ints.)
Fixes bug 24733; not in any released version of tor.
