Clean up bad layout files in zuul tests

Clean up the bad layout files in the zuul tests by removing a redundant
file (bad_pipeline and bad_pipeline1.yaml were identical). Annotate the
reason the layout is bad in each file. Finally remove a redundant swift
section. Both bad switf sections were failing for the same reason, a
missing name entry.
