Subject: Compile and link 'libdome_key_event_source_simulator'

Turn this into a build dependency with Make.

(https://stackoverflow.com/users/155423/shepmaster) answer on Stack
Overflow to sort out getting Cargo the search path for the static
library:

For some reason I wasn't able to get it to work by just putting the
library into `./target/debug/deps/`. I had to explicitly tell Cargo to
put that in the search path.

Also, we need to use `std::env` instead of the `env!` macro to get the
`PROFILE` environment variable, otherwise it won't be initialised at the
right time, as described in the Rust docs:

> Because these variables are not yet set when the build script is
> compiled, the above example using env! won't work and instead you'll
> need to retrieve the values when the build script is run
