Rust source files (*.rs) don't have to be executable.
This is required to avoid the following error.

error[E0308]: `#[panic_handler]` function has wrong type
--> rmm/src/panic.rs:15:1

15 | pub extern "C" fn panic_handler(_info: &core::panic::PanicInfo<'_>) -> ! {
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected "Rust" fn, found "C" fn

= note: expected signature `for<'a, 'b> fn(&'a core::panic::PanicInfo<'b>) -> _`
found signature `extern "C" for<'a, 'b> fn(&'a core::panic::PanicInfo<'b>) -> _`
```
This is required to avoid the following errors. ``` error: the `#[alloc_error_handler]` in islet_rmm conflicts with allocation error handler in: std error[E0152]: duplicate lang item in crate `std` (which `kani` depends on): `panic_impl`. error: aborting due to previous error error: could not compile `fvp` (bin "fvp") due to 2 previous errors error: Failed to execute cargo (exit status: 101). Found 2 compilation errors. make: *** [Makefile:8: verify] Error 1 ```
This is required to resolve a conflict in supporting model checking.
Usage 1) Verify islet using model checking (in plat/fvp) $ make verify Usage 2) Remove generated output (in plat/fvp) $ make clean

This PR prepares for basic environment setup for model checking. Slightly modified kani has been used to verify with
aarch64target instead ofx86_64target, yet using the unmodified one for normal usage would be fine. Verification harnesses will be added later.
