ipc/compat_sys_msgrcv: change msgtyp type from long to compat_long_t

commit 291fdb0bcebd5e8db6af767c1fdc522167dad73d upstream.

Change the type of compat_sys_msgrcv's msgtyp parameter from long
to compat_long_t, since compat user space passes only a 32 bit signed
value.
Let the compat wrapper do proper sign extension to 64 bit of this
parameter.
