Make dummy-bash -> dummy-glibc dependency require archful. This avoids
potential race condition where order of dependency processing can result in
different packages being pulled in. The tests where this could happen are
updated.
Make dummy-glibc-debuginfo depend on dummy-glibc-debuginfo-common.
The filenames for the repo no longer include hash, and sqlite databases are not
generated.
