roles/gitea: Install from upstream binary

I seem to have forgotten how I got the RPM for Gitea.  I think I built
it, but I cannot find the spec file, nor the RPM package.  Since this is
clearly not reproducible, I decided to switch to using the binary
provided by upstream for now, until either I or Fedora get around to
making a better RPM.

Installing Gitea from the upstream binary is simple: just download it
and copy it to `/usr/local/bin`.  Of course, the OS user and systemd
unit have to be managed by configuration policy when it's installed this
way.
