The check suffered from various flaws.
First, due to missing quotes around $initrd, 'wc -l' would always see
1 line no matter how many results the find returned.
Second, echo adds a line break making 'wc -l' count 1 even for empty
string. We need to add a check for empty string.

Closes-Bug: #1506692
The centos-minimal approach of using rinse does not, it turns out, work
on centos. That's a bummer. It's also rather heavyweight. Instead, with
minor machinations, we can just use yum itself pointed at a chroot.
Also adding fedora-minimal element which creates a fedora image using
the new yum-minimal approach.
