libmodprobe: Do not reload modules previously instantiated
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
