init-storage: Copy file contexts from rootfs 

Apparently, BusyBox's `cp` does NOT copy SELinux contexts when the `-a`
argument is specified.  This differs from GNU coreutils's `cp`, and
explains why the files copied from the rootfs image to the persistent
storage volume were not being labelled correctly.  The `-c` argument is
required.

Now that files are labelled correctly when they are copied, the step to
run `restorecon` is no longer necessary.
