Ian Wienand cb0e0e903d Use dnf to cleanup old kernels
As described in the comment, there is a dnf equivalent of this command
that doesn't require us installing yum-utils (which drags in yum on
dnf-only systems such as f23)

This is a small consequence to this -- due to us not installing
yum-utils some installs will now be completely yum free.  This causes
a breakage in ironic-agent 99-remove-extra-packages where we remove
the yum package.  There is a long-standing bug/feature where missing
packages in a group of packages do not cause yum/dnf to exit with
failure, but uninstalling a single package will.  Because we have made
the systems yum-free, the uninstall of yum can fail in this corner
case.

It has always been like this, so I'm in favour of the "ain't broke"
approach.  To work-around this, I have just put yum into the existing
list of packages to be cleaned up.  I have added a note to the yum
installer taking note of this behaviour for future reference.
