afs: proc cells and rootcell are writeable
Both proc files are writeable and used for configuring cells. But
there is missing correct mode flag for writeable files. Without
this patch both proc files are read only.
[ It turns out they aren't really read-only, since root can write to
them even if the write bit isn't set due to CAP_DAC_OVERRIDE ]
