Switch Oracle DB container image to new 21-slim-faststart flavour

[Sanne]

@gvenzl is now publishing a new kind of Oracle DB container images called "faststart" - these are slighly larger to download but are sginificantly faster to bootstrap, making them more suitable for Quarkus dev-services.

With this PR I'm making them the new default for Quarkus; the change should be transparent to end users.

Also it would seem that the slightly larger file size has negligible impact on pull times (atlhough this will likely vary from system to system); see gvenzl/oci-oracle-xe#36
