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,
                   from <command-line>:32:

  usr/include/asm-generic/ipcbuf.h:32:2: error: unknown type name `__kernel_ulong_t'

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.
