unix: ensure struct msghdr is zeroed in recvmmsg (#3419)
With MUSL libc, the struct msghdr is padded to align with the types used
in the Linux kernel headers (int vs size_t). When the padding was not
zeroed, the syscall would return EMSGSIZE because the random bytes in
the padding would be read by kernel as part of the size_t type.
