setfiles isn't supported on the vfat /boot/efi partition. Add it to
the skip list.
Tested on Fujitsu Server successfully.

Currently, the cleanup script is using existence of
semanage binary to check if selinux is enabled. However
this is misleading and can lead to problems when selinux
is disabled in a system where the binary exist.
This patch changes the detection logic to use /sys/fs/selinux
directory which is a in-memory filesystem created only when
selinux is really enabled.

As described in the comments inline, on a selinux enabled kernel (such
as a centos build host) you need to have permissions to change the
contexts to those the kernel doesn't understand -- such as when you're
building a fedora image.
For some reason, setfiles has an arbitrary limit of 10 errors before
it stops. I believe we previously had 9 errors (this mean 9
mis-labeled files, which were just waiting to cause problems).
Something changed with F26 setfiles and it started erroring
immediately, which lead to investigation. Infra builds, on
non-selinux Ubuntu kernel's, would not have hit this issue.
This means we need to move this to run with a manual chroot into the
image under restorecon.
I'm really not sure why ironic-agent removes all the selinux tools
from the image, it seems like an over-optimisation (it's been like
that since Id6333ca5d99716ccad75ea1964896acf371fa72a). Keep them so
we can run the relabel.
