modules: Enabled dynamic debugging for staging modules

Browse source 
Driver modules from the staging directory are marked 'tainted'
by module.c. Subsequently, tainted modules are denied dynamic
debugging. This is unwanted behavior, since staging modules should
be able to use the dynamic debugging mechanism.

Please merge this also into the staging-linus branch.
