package_rpm/dev/ipk/tar: Drop unused functions

The package_xxx_install functions date from a different era and are not used by
anything. In the rpm case, they're simply unimplemented, in the tar case they're
using broken whitespace and deprecated functions. We might as well clean
out the old broken unused code.
