install everything in /usr

This patch is needed for the /usr-move feature
https://fedoraproject.org/wiki/Features/UsrMove

This package requires now 'filesystem' >= 3, which is only installable
on a system which has /bin, /sbin, /lib, /lib64 as symlinks to /usr and
not regular directories. The 'filesystem' package acts as a guard, to
prevent *this* package to be installed on old unconverted systems.

New installations will have the 'filesystem' >=3 layout right away, old
installations need to be converted with anaconda or dracut first; only
after that, the 'filesystem' package, and also *this* package can be
installed.

Packages *should* not install files in /bin, /sbin, /lib, /lib64, but
only in the corresponding directories in /usr. Packages *must* not
install conflicting files with the same names in the corresponding
directories in / and /usr. Especially compatibilty symlinks must not be
installed.

Feel free to modify any of the changes to the spec file, but keep the
above in mind.
