wireshark: drop gmodule.h include to avoid glib warnings

The wireshark address.h header uses 'g_memdup2' but this triggers
warnings under clang due to the max version cap:

It is unclear why clang warns, but gcc does not. Our plugin doesn't
actually use the inline helper in address.h that references g_memdup2,
but we get the warning regardless.

Interestingly removing the 'gmodule.h' include avoids the warning. Since
there is nothing in plugin.c that appears to need gmodule.h, removing it
should be safe & done regardless.
