std: fix msghdr and cmsghdr when using musl libc
glibc and linux kernel use size_t for some field lengths while POSIX and
musl use int. This bug would have caused breakage the first time someone
tried to call sendmsg on a 64-bit big endian system when linking musl
libc.
my opinion:
* msghdr.iovlen: kernel and glibc have it right. This field should
definitely be size_t. With int, the padding bytes are wasted for no
reason.
* msghdr.controllen: POSIX and musl have it right. 4 bytes is plenty for
the length, and it saves 4 bytes next to flags.
* cmsghdr.len: POSIX and musl have it right. 4 bytes is plenty for the
length, and it saves 4 bytes since the other fields are also 32-bits
each.
