Add build instruction for Fedora-based distro (Centos, Redhat)

[rustysys-dev]

Do you want to request a feature or report a bug?
bug/feature ?
documentation on how to create RPM for Fedora
documentation on building binaries for Fedora

What is the current behavior?
There seems to be only documentation on building binaries on Ubuntu, which I would be comfortable dismissing and just using the RPMs provided on your site, however the RPM packages are ~260MB while the DEB packages are ~170MB which I feel is a huge difference.

What is the expected behavior?
There shouldn't be such a large disparity in package sizes.
There should be a more universal process to creating binaries.

Which versions of DesktopEditors, and which OS are affected by this issue? Did this work in previous versions of DesktopEditors?
N/A

Main difference in size - in libcef.so and this is 3rd party library and I'm not sure we can control it size

And yes, I agree - currently there is no instruction how to build project on Fedora-based system - but we are planning to add it

I'll move this issue to another repo
