qga/commands-posix: Fix listing ifaces for Solaris
The code for guest-network-get-interfaces needs a couple of small
adjustments for Solaris:
- The results from SIOCGIFHWADDR are documented as being in ifr_addr,
not ifr_hwaddr (ifr_hwaddr doesn't exist on Solaris).
- The implementation of guest_get_network_stats is Linux-specific, so
hide it under #ifdef CONFIG_LINUX. On non-Linux, we just won't
provide network interface stats.
