Masahiro Yamada 9ef0e00418 arch: msgbuf.h: make uapi asm/msgbuf.h self-contained
Userspace cannot compile <asm/msgbuf.h> due to some missing type
definitions.  For example, building it for x86 fails as follows:

    CC      usr/include/asm/msgbuf.h.s
  In file included from usr/include/asm/msgbuf.h:6:0,
                   from <command-line>:32:

    struct ipc64_perm msg_perm;

    __kernel_pid_t msg_lspid; /* pid of last msgsnd */
    ^~~~~~~~~~~~~~
  usr/include/asm-generic/msgbuf.h:42:2: error: unknown type name `__kernel_pid_t'
    __kernel_pid_t msg_lrpid; /* last receive pid */
    ^~~~~~~~~~~~~~

It is just a matter of missing include directive.

Include <asm/ipcbuf.h> to make it self-contained, and add it to
the compile-test coverage.
