Subject: arch: ipcbuf.h: make uapi asm/ipcbuf.h self-contained
Userspace cannot compile <asm/ipcbuf.h> due to some missing type
definitions. For example, building it for x86 fails as follows:
CC usr/include/asm/ipcbuf.h.s
In file included from ./usr/include/asm/ipcbuf.h:1:0,

It is just a matter of missing include directive.
Include <linux/posix_types.h> to make it self-contained, and add it to
the compile-test coverage.
