insmod.sh: Support 'rmmod' directive

Browse source 
Some mechanisms (e.g., initramfs module lists) may be overzealous in
what modules get loaded on a system. It can save resources to remove
certain modules when we know they are going to be unused -- for example,
extraneous panel drivers only needed for other devices within a given
device family.

Bug: 360934165
Test: `rmmod|<module_name>.ko` added to init.insmod.<device>.cfg
