USB: usb-storage: added missing MODULE_LICENSE("GPL") for usb-storage ums-* modules

The lack of a MODULE_LICENSE macro in ums-* subdrivers prevented them
from loading. Needs to be applied after Alan Stern's usb-storage
subdriver separation patchset. Also added missing MODULE_DESCRIPTION and
MODULE_AUTHOR entries.
