pulsecore/packet: avoid redefinition of pa_packet structure

packet.h defines:

  typedef struct pa_packet pa_packet;

and packet.c defines:

  typedef struct pa_packet {
    ...
  } pa_packet;

With old versions of gcc (such as gcc 4.5) this causes a redefinition
error at compile time:

pulsecore/packet.c:43:3: error: redefinition of typedef 'pa_packet'
pulsecore/packet.h:26:26: note: previous declaration of 'pa_packet' was here

In order to fix this, this commit changes the definition in packet.c
to just:

  struct pa_packet {
    ...
  };

This way, the contents of the structure remain opaque to users of
pa_packet outside packet.c, and the 'pa_packet' type remains usable.
