Missing OEL8/RHEL8/Fedora installation prerequisites

[denismakogon]

I was trying to build an image based on something that is not Debian.
I found that there has to be a lot of software being installed before installing the FFmpeg.

It would be good to have a doc updated with necessary bits of software that have to be installed before executing the install script.

I'll post a solution here:

RUN microdnf update --nodocs -y && \
    microdnf clean all && \
    microdnf update --nodocs -y && \
    microdnf install gcc gcc-c++ make curl git python3 rust cargo tar gzip findutils diffutils file xz perl perl-Data-Dumper -y && \
    microdnf clean all

maybe someone will be faster than I to submit the PR.
