Allow dnf to be used as pkg manager for Fedora #2255

[vegerot]

Description

(Description of what the PR does, such as fixes # {issue number})
@guystreeter pointed out he had issues using dev_setup.sh on Fedora (#2255 )
He mentioned that replacing os_is fedora for os_is_like fedora resolved his issue. So I substituted the statement elif os_is_like fedora for elif os_is_like fedora || os_is fedora. Which should fix the issue

How to test

Run ./dev_setup.sh on systems similar to:

$ cat /etc/os-release 
NAME=Fedora
VERSION="30 (Workstation Edition)"
ID=fedora
VERSION_ID=30

Thanks @vegerot looks good. Will merge this as soon as the CLA has landed.

[forslund]

Hi again @vegerot did you get a CLA mail or has it stalled someplace along the way? Let us know if wew need to look at anything.

[vegerot]

@forslund I am not sure what the issue is. I got the email last week and thought I filled it all out. Please let me know how best to proceed.

[forslund]

I will poke around here and see if the hello-sign thing has been missed on our end. Thanks for letting us know.

[vegerot]

No problem. Hopefully everything checks out and can get merged soon

[forslund]

I've gotten confirmation that your CLA has been received but you haven't been entered into the official list of signers yet.

I'm updating status manually for now.

Many thanks for this contribution, it looks good all over. Sorry for the delay with the administration.

Merging!
