x86/ftrace: Use text_poke()
Move ftrace over to using the generic x86 text_poke functions; this
avoids having a second/different copy of that code around.
This also avoids ftrace violating the (new) W^X rule and avoids
fragmenting the kernel text page-tables, due to no longer having to
toggle them RW.
