Travis: replace "default configuration by "full configuration"

For the one long job with ASan, use the full configuration.

We get more coverage this way, at the cost of a slightly longer
runtime which we can afford since the "enumerated configurations" job
is slower.

Add a default-configuration build to the "basic checks" job. This job
is fairly quick (no ASan, no SSL testing).
