CI PCP Win: patch rather than using old version

IP*PKTINFO is defined by the Mingw-w64 headers but the structs
(eg. msghdr or cmsghdr) as defined in RFC 3542 seem to be called
differently (WSAMSG, WSACMSGHDR).

So the compat will be perhaps still required unless PCP adds support
for Win structure names. The other changes are just fixing Win-specific
headers (which may be fixed in PCP upstream eventually).

Also moved dummy Git identity setting to enfironment.sh (is now needed
also for MSW).
