In the short term this will be used to help implement support for
multiple kernel module directories but it may be useful in other
contexts as well.

Add a remove method which will unload a given module from the kernel,
along with any modules it depended on, assuming those modules are now
unused.

Steve Muckle 18b981ea7c create libmodprobe, integrate into first_stage_init
Modprobe functionality is required both within first stage init and also
as a standalone binary. Create a library for this using and extending
the logic in modalias_handler.cpp.

First stage init will attempt to load modules from /lib/modules.
