wireshark: Drop glib dependency

The only function that we currently use from glib is g_sprintf().
That's a very big gun for such small target. Not only that, but
we've silently relied on wireshark dragging in the glib. Replace
the g_sprintf() with plain sprinf() so that we can drop the glib
dependency.
