powerpc: switch to generic sys_execve()/kernel_execve()
the only non-obvious part is that current_pt_regs() is really needed here - task_pt_regs() is NULL for kernel threads; it's OK for ptrace uses (the thing task_pt_regs() is intended for), but not for us. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
