Bash completion for bpftool gets two minor improvements in this patch. Move the detection of attach types for "bpftool cgroup attach" outside of the "case/esac" bloc, where we cannot reuse our variable holding the list of supported attach types as a pattern list. After the change, we have only one list of cgroup attach types to update when new types are added, instead of the former two lists. Also rename the variables holding lists of names for program types, map types, and attach types, to make them more unique. This can make it slightly easier to point people to the relevant variables to update, but the main objective here is to help run a script to check that bash completion is up-to-date with bpftool's source code.
