std.os.linux: remove unnecessary warnings from sendmmsg
The one about INT_MAX is self-evident from the type system. The one about kernel having bad types doesn't seem accurate as I checked the source code and it uses size_t for all the appropriate types, matching the libc struct definition for msghdr and msghdr_const.
