[S390] sys_personality: follow u_long to unsigned int conversion

commit 485d527686850d68a0e9006dd9904f19f122485e "sys_personality: change
sys_personality() to accept "unsigned int" instead of u_long" changed
the syscall interface for sys_personality.
Just follow the common code change in our arch code to avoid confusion.
