cargo: rejigger crate type

convert to hybrid crate, with arch-dependent stuff as a ‘bin’ crate,
with the underlying support in ‘lib’.

the reason for this change is to allow for automated unit-testing on
the device-independent bits. to facilitate this, a ‘t’ alias is
provided which will run the unit tests. this target assumes you're on
a linux system, but you can't have everything.
