ueventd: require opt-in for modalias handling

Some devices have modules.alias and modules.dep for modprobe and other
purposes but do not want to opt into ueventd auto loading their
modules.  Therefore we add a flag that can be added to ueventd
configuration files to opt into this behavior.

Test: check that modules are loaded with this opt-in
Test: check that modules are not loaded without this opt-in
