Why? IMHO those two TFM files are to be handled *exactly* the same
way as all other generated files by TeXLive, which puts things by
default into a directory tree in $HOME.
It would be possible to have this cache directory tree somewhere else
(by adjusting environment variables, for example), but then *all*
generated files should be placed there. I doubt that this is the
right thing for Joe User...
