binutils: remove autoreconfHook on iOS

This was added in ebc2243 ("binutils: Add iOS as a supported
platform"), at the same time as a patch.  That patch was removed in
045c2d2 ("binutils-unwrapped: remove broken iOS patch"), and I'm
not sure what other reason there would be for autoreconfHook to be
required specifically for iOS, so I think we can remove it.  It's not
possible to test since iOS cross has been broken for months, and
keeping this around is making other refactors (like adding cross
binutils packages) harder.
