vsprintf: add %ps that is the same as %pS but is like %pf
On PowerPC64 function pointers do not point directly at the functions,
but instead point to pointers to the functions. The output of %pF expects
to point to a pointer to the function, whereas %pS will show the function
itself.
mcount returns the direct pointer to the function and not the pointer to
the pointer. Thus %pS must be used to show this. The function tracer
requires printing of the functions without offsets and uses the %pf
instead.
%pF produces run_local_timers+0x4/0x1f
%pf produces just run_local_timers
For PowerPC64, we need to use the direct pointer, and we only have
%pS which will produce .run_local_timers+0x4/0x1f
This patch creates a %ps that matches the %pf as %pS matches %pF.
