internal/socket: add ppc system call definitions, for use with gccgo

Add system call definitions for 32-bit PowerPC (ppc). These are
expected to be used with gccgo, as gc does not have a suitable code
generator.

* Define the system call numbers for recvmmsg() and sendmmsg()
* Enable the 32-bit definitions of cmsghdr, iovec, and msghdr structures
* Add the structure definitions generated by godefs

This has been tested with a program that listens for UDP connections
and then sends back multiple messages with PacketConn.WriteBatch.

Fixes golang/go#45677
