Revert "docker: Enable features explicitly in test-full"

This reverts commit 5e8a7fe673.

It's hard to get all images to have all these packages, the usual
"FEATURES" and "require" mechanism doesn't scale with so many features.
With that change, the test basically only works in ubuntu.

Until a better way comes up, leave the feature enabling to ./configure
detection.

But don't remove the "-e" removal.
