mobile/gsm48_mm.h: mark some structures as 'packed'
In several code paths we put / push structures from 'gsm48_mm.h' into
the message buffers, so then they're unpacked by the message receivers.
The AddressSanitizer complains about unaligned pointer access and
potentially unexpected behaviour. Let's fix this by explicitly
marking those structures as 'packed'.
