Carlos Goncalves 670df3326d Fix regex for mirror URL substitution
The base URL of EPEL repository installed by the epel-release package in
CentOS 8 at least now defaults to https.

The error seen when building an CentOS 8 image was:
"Error: Cannot find a valid baseurl for repo: epel"

This patch fixes it so that it will always match regardless of being
http or https.
