This allows us to take advantage of the `testing` package. It also gives
the resulting test binary common command line arguments (same as `go
test`).
Tests need to be compiled with `go test -c`, which injects a `Main()`
that calls the Test* functions.
This is not supported by the golang rpm macros. Thus, build this binary
by calling `go test -c` directly, but taking care to pass the same
linker flags as the `%gobuild` macro.
Mark the test binary with the `integration` build constraint, so that
`go test ./...` doesn't pick them up. That's only for unit tests.
The idea is to move all other test binaries to this scheme as well.

rpmmd looked at the CACHE_DIRECTORY environment variable to set a path
for the dnf repository cache. Aside from being a smelly thing to do
from a library, this breaks osbuild-pipeline and osbuild-dnf-json-tests,
which don't run as systemd services and thus don't have CACHE_DIRECTORY
set.
Explicitly pass the cache directory to rpmmd. Keep using a path based on
CACHE_DIRECTORY for osbuild-composer. Use the user's `.cache` directory
for osbuild-pipeline and a temporary directory for the tests.
the name was misleading because the function could do more than just
download package list. In PushComposeRequest it is also used to fetch
checksums for the repositories, therefore I decided to rename it to
reflect this usage.
