Fix win32 builds by using the SLIRP_PACKED definition

A packed struct needs different gcc attributes for compilations
with MinGW compilers because glib-2.0 adds compiler flag
-mms-bitfields which modifies the packing algorithm.

Attribute gcc_struct reverses the negative effects of -mms-bitfields.

We already have the SLIRP_PACKED definition for that, use it.
