x86: mark kprobe templates as character arrays, not single characters

Browse source

They really are, and the "take the address of a single character" makes
the string fortification code unhappy (it believes that you can now only
acccess one byte, rather than a byte range, and then raises errors for
the memory copies going on in there).

We could now remove a few 'addressof' operators (since arrays naturally
degrade to pointers), but this is the minimal patch that just changes
the C prototypes of those template arrays (the templates themselves are
defined in inline asm).
