Description of problem:
When adding new copr repositories by using "sudo dnf copr enable xy" the repository files are only readable for root which causes "dnf repolist" to claim the copr repository as not readable.

Version-Release number of selected component (if applicable):
dnf-plugins-core-0.1.9-1.fc22.noarch

How reproducible:
allways

Steps to Reproduce:
1. Run "sudo dnf copr enable" for a copr repo you want to use
2. Run "dnf repolist" to see all available repos on your machine

Actual results:
The copr repo-file is not readable to your user due to wrong file premissions.

Expected results:
The copr repo-file should be readable to all users like other repos.

Additional info:
Doing a "sudo chmod a+x" on the copr repo file solves the problem
