Simplifies a number of aspects of the RPM build, including moving
.copr/Makefile into the "fedora/" folder (and leaving a symlink),
removing the jellyfin-web build components, and renaming it
jellyfin-server like Debian did.
This adds enhancements so that Fedora/EL packages can be automatically
built in COPR when a webhook is received. A typical webhook could be
for tagging events for example or even a "Release" webhook to only
build releases.
