packaging: make dockerrpm fedora target more generic

Fedora moves fast in version numbers, and often with Mercurial packaging being
backwards compatible. Thus, only aim for providing built-in support for latest
Fedora version, and make it easy to update.

With this refactoring, 'dockerrpm fedora31' also works.

'dockerrpm fedora' will use the 'fedora:latest' Docker image.
