I'm not aware of a tool to do the conversion.  However there may be one 
that I'm not aware of.

I wasn't aware that you could put sub-directories in 
/etc/portage/package.use.  I've always had to put the files directly in 
that directory, not sub-directories.  As such, my files have names like 
sys-apps-util-linux to avoid naming collisions.  Perhaps things have 
changed since I last tried to use a sub-directory or I am misremembering.

I think it should be relatively easy to script reading the line, 
extracting the package name, munging the name, and writing the entire 
unmodified line to a new file based on the munged name.  If directories 
work, create and populate them without munging names.
