%files section for it.
Fixes: #3701
Signed-off-by: Brian J. Murrell <brian@interlinx.bc.ca>
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.
