ptrace: do not print data argument of some requests on sparc

On sparc, kernel ignores data argument of PTRACE_GETREGS,
PTRACE_SETREGS, PTRACE_GETFPREGS, and PTRACE_SETFPREGS requests.

* process.c (SYS_FUNC(ptrace)) [SPARC || SPARC64]: Return RVAL_DECODED
right after printing addr argument if request is one of PTRACE_GETREGS,
PTRACE_SETREGS, PTRACE_GETFPREGS, or PTRACE_SETFPREGS.
