Description of problem:

When running fedora-review the time spent performing the CheckOwnDirs test is way too long.

fedora-review -x CheckOwnDirs -m fedora-rawhide-x86_64 -n R-highlight

real	6m16.870s
user	2m28.194s
sys	0m46.464s

fedora-review -m fedora-rawhide-x86_64 -n R-highlight

real	70m38.014s
user	66m8.734s
sys	1m33.922s

I,e, by excluding the CheckOwnDirs test the running time of fedora-review is reduced from 70 minutes to 6 minutes.

Version-Release number of selected component (if applicable):
fedora-review-0.6.0-2.fc23.noarch

How reproducible:
Always

Steps to Reproduce:
1. Compare running fedora-review with and without the -x CheckOwnDirs flag

Actual results:
Excluding the CheckOwnDirs test reduces the running time with about one hour.

Expected results:
This test should not add significantly to the running time of fedora-review

Additional info:

Most of the time is used for running:
dnf repoquery -q -C --requires --resolve <somepackage>

This takes a few minutes per package:

$ time dnf repoquery -q -C --requires --resolve glibc
glibc-0:2.22-7.fc23.i686
glibc-0:2.22-7.fc23.x86_64
glibc-common-0:2.22-7.fc23.x86_64
nss-softokn-freebl-0:3.21.0-1.1.fc23.i686
nss-softokn-freebl-0:3.21.0-1.1.fc23.x86_64

real	3m49.104s
user	3m46.256s
sys	0m2.396s

Without the --resolve flag it returns in less than a second.

So if you could reimplement the test not using the --resolve flag it would be much faster. Or if dnf didn't take that much time when the --resolve flag was used...
