Use a specific cross_file on iOS cross compilation.

We need to set the property `needs_exe_wrapper` to true for
x86_64 cross compilation.

Else, meson will try to detect if we could run the cross
compiled executable, and because it is the same arch, it will
assume we can. So it will try to sanity check and execute the
cross compiled binary. Then fails.
