Fedora 33+: spectool -g downloads text sources/patches as gzipped; fix in updates-testing

[Miro Hrončok]

Hello packagers,

if you have rpmdevtools-9.3-2.fc33 (or .fc34) installed and you run `spectool 
-g` on spec files with remote text sources/patches, such as git(hub|lab)/pagure 
patches, or signatures/keys:

Patch1:  https://pagure.io/rpmdevtools/pull-request/77.patch
Patch2:  https://github.com/prusa3d/PrusaSlicer/commit/44f71f0ed1.patch
Source1: https://www.python.org/.../Python-%%7Bversion%7D.tar.xz.asc
Source2: https://www.python.org/static/files/pubkeys.txt
... etc ...

They might be downloaded gzipped, depending on the configuration of the 
webserver that serves them. They are known to be downloaded gzipped at least 
from Pagure and GitHub.

The fix is available in rpmdevtools-9.3-3.fc33 (or .fc34).

Fedora 33 update: https://bodhi.fedoraproject.org/updates/FEDORA-2021-cb926a505c

All Fedora/EL/... package maintainers running Fedora 33, 34 or ELN/RHEL9 are 
advised to update.

$ sudo dnf upgrade --enablerepo=updates-testing rpmdevtools

The affected version never reached Fedora 32 or RHEL 7/8.
