As ocaml/opam#4791 removed support for detection of available packages on Fedora and according to @kit-ty-kate the detection is very dependent on the system, this test is too flaky to be useful.

#4790 shows that
yum listis an unreliable command to use and no options seems to be available to make it so.#4759 also shows that RHEL-based distributions have virtual packages that opam is not taking into account.
For these two reasons I propose we simply remove the use of
yum listin favour ofrpm -qawhich seems way more reliable and leaps faster (~0.1s vs. ~2s!!).Sadly we incidently disable the detection of available packages and thus revert to the behaviour of the opam-depext plugin.
IMO this is not a big deal as only a few distributions that we support actually have it disabled as well due to the method to acquire the data being either incomplete or too tedious/unreliable. This is the case currently (in 2.1.0) for FreeBSD, Gentoo, Homebrew, NetBSD and OpenBSD
