Add missing godoc comments for xfrm stats (#433)

Add missing godoc comments matching the kernel documentation, see https://www.kernel.org/doc/html/latest/networking/xfrm_proc.html Also rename the `xfrm*.go` files to have a `net_` prefix, as the respective file is found in the `net/` sub-directory and this matches filenames for other network-related stats.
