[PATCH v4 05/20] powerpc: Remove direct call to personality syscall handler

Syscall handlers should not be invoked internally by their symbol names,
as these symbols defined by the architecture-defined SYSCALL_DEFINE
macro. Fortunately, in the case of ppc64_personality, its call to
sys_personality can be replaced with an invocation to the
equivalent ksys_personality inline helper in <linux/syscalls.h>.

V1 -> V2: Use inline helper to deduplicate bodies in compat/regular
implementations.
V3 -> V4: Move to be applied before syscall wrapper.
