For modprobe operation.
For an interlocking driver set of about 50 modules, the impact of
their dependencies resulted in a 30 second impact in boot time
trying to load previously loaded modules. This impact is handily
eliminated by keeping a list of modules paths that have been loaded
and skipping them proactively.
Test: Confirmed device boot and 50 module set of drivers functions.
Test: libmodprobe_tests

Add support to specify module parameters in LoadWithAliases. These
parameters will be appended to any which are specified for the module in
modules.options.

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.

Make the module name canonical in LoadWithAliases so it may be used
more easily from outside the class.

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.
