simple patch as proof of concept of possible solution for the current python3 version

Description of problem:
yum used to allow formatting with -qf with the --tree-whatrequires option.  dnf ignores --qf with --tree.  dnf hardcodes the output format of --tree.  It would be great if dnf could use qf like yum did when using --tree.

I have gotten this to work with a tiny patch (attached) to:
/usr/lib/python3.5/site-packages/dnf-plugins/repoquery.py

The fact this feature already wasn't in there seems like just an oversight.

The python2 version is pretty much identical, let me know if I should provide a patch for that also.  It's been a while since I submitted patches, let me know if I'm formatting them wrong.



Version-Release number of selected component (if applicable):
python3-dnf-plugins-core-0.1.21-3.fc24.noarch


How reproducible:
always


Steps to Reproduce:
1. dnf repoquery --whatrequires gtk2 --installed --arch=$MACHTYPE,noarch --tree --queryformat '%{name}' --resolve


Actual results:
gimp-2:2.8.20-1.fc24.x86_64
 \_ xsane-gimp-0.999-20.fc24.x86_64 [47: ...]
gtk2-devel-2.24.31-1.fc24.x86_64
gtk2-immodule-xim-2.24.31-1.fc24.x86_64


Expected results:
gimp
 \_ xsane-gimp [47: ...]
gtk2-devel
gtk2-immodule-xim


Additional info:
I need the name-only format for a script I wrote to work with yum, and it's not possible to just regex derive name from NERV because the dash-number boundary can be ambiguous.
