centos7 updates are sporadic and this has not
been addressed, so we change to building from
source and patching in the fix.
*** Testing
We want to sanity check xmlwf, an xml format checker.
Build and boot iso, log in, then
$ xmlwf -c -d . /tmp/firewalld/zones/public.xml
$ cat public.xml
which should be a copy of the original.
