c_run_key_action(): Fix segfault on `in_mode`

Finally figured out where the problem was with the `in_mode` on my
`CKeyActionResult` getting freed too early.

It happens because we're trying to use the reference to the `in_mode`
slice from the `KeyActionResult` returned by
`run_key_action_for_mode()`. We were putting that reference in the
`in_mode` of the `CKeyActionResult` returned by `c_run_key_action()`,
but it would get freed in that function.

In order to make it last indefinitely, we needed to convert it into a
raw boxed pointer to prevent Rust from deallocating it. This does mean
we now have a memory leak, but we'll just have to make a call into Rust
to free it from the C code.
