Fedora images not supported

[aisler-ma]

Fedora is not supported by the gem and does not build.

It is not quite as simple as adding the fedora builds form the Github. Fedora zips only ship with 64-bit shared libs. Thus, we need to copy them as well and add the lib64 path to the build path.

Sorry in case this is obvious for most people here, but in case anyone is trying to install or-tools gem on Fedora:

You can do it by installing or-tools library via Homebrew on Linux. Then you do:

gem install or-tools -- --with-or-tools-dir=/home/linuxbrew/.linuxbrew

Or if you use a Gemfile:

bundle config build.or-tools --with-or-tools-dir=/home/linuxbrew/.linuxbrew

Tested on Fedora 43. It would probably work on most distros as well.
