Add MSG_SOCK_DEVMEM from Linux 6.12 to bits/socket.h

Linux 6.12 adds a constant MSG_SOCK_DEVMEM (recall that various
constants such as this one are defined in the non-uapi linux/socket.h
but still form part of the kernel/userspace interface, so that
non-uapi header is one that needs checking each release for new such
constants).  Add it to glibc's bits/socket.h.

Tested for x86_64.
