dtrace: adjust FBT entry probe dection for OL7

On OL7, function prologues can be prefixed by a (5-byte) call
instruction on x86_64, which breaks the logic to determine if
we can place an FBT entry probe on that function.  The new logic
accounts for the possibility that the anticipated prologue does
not show up as first instruction of the function.
