[tex-live] Getnonfreefonts does not enable map files when fonts are already installed

[Axel Kielhorn]

Hello!

After instaling TL 2009 I ran getnonfreefonts-sys to update the  
nonfree fonts.
It told me that the fonts are alreday installed, which is correct and  
it did't enable the map files, which is not correct.

I enabled the map files manually and everything is fine now, but this  
could cause a problem when updating from TL 2008 with the nonfree  
fonts in texmf-local.
