Ian Wienand 5bc9e87da1 centos: avoid head pipe failure
I just saw in the trace output of a failure

  > grep -o 'CentOS-.[^>]*GenericCloud-.[^>]*.qcow2'
  > sort -r
  > head -1
  sort: fflush failed: 'standard output': Broken pipe
  sort: write error

i.e. the "head -1" has exited after reading one line, but "sort -r"
still wants to write and thus has hit a pipe failure, and because we
run with "-o pipefail" this has halted the script.

This seems like it has been there more or less forever, maybe we just
got lucky hitting it now?  Anyway, we can work around this by using a
process substitution and passing the output of this into head, this
way we won't hit a pipe failure.

I also updated the fedora path as it does the same thing.

Use Fedora cloud images as the baseline for built disk images. For further
details see the redhat-common README.

Releases
--------

This element targets the current and previous version of Fedora; these
values clearly changes over time.  To fix the version set the
`DIB_RELEASE` variable to the Fedora version (e.g. ``35``).  The
default value is the current best supported version (i.e. it may
change upward at any given release to support the next Fedora).


Environment Variables
---------------------

DIB_DISTRIBUTION_MIRROR:
   :Required: No
   :Default: None
   :Description: To use a Fedora Yum mirror, set this variable to the mirror URL
                 before running bin/disk-image-create. This URL should point to
                 the directory containing the ``releases/updates/development``
                 and ``extras`` directories.
   :Example: ``DIB\_DISTRIBUTION\_MIRROR=http://download.fedoraproject.org/pub/fedora/linux``
