This performs a lot of bugfixing and general cleanup to the
Fedora/CentOS builds, including moving the create_tarball into the
docker-build.sh script, remove some old long versions from the spec
file, correcting several bugs with the Docker environment including
splitting them into more discrete layers, and finally making sure
jellyfin-web is included properly in the RPM.
1. Update README.md to remove some old info
2. Remove common.build.sh from all the build scripts
3. Remove common.build.sh script
4. Remove the docker folder as this isn't used at all
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.
