rawmidi: Use the standard types for snd_rawmidi_framing_tstamp_t definition

Browse source 
Using the kernel-specific types like __u8 breaks the compilation of
applications.  Also we need the packed attribute.

Although we may want to move to an opaque type later, let's put the
workaround at first.
