ci: Build with --otel on dev distros

This just builds the OTEL stuff for the Fedora Rawhide and Alpine Edge
distributions.

If we ever get test cases covering OTEL we can figure out the best way
to do it in the ci.yaml, but right now I don't see the point in building
OTEL in every test configuration there...
