fix --workdir

Fixes #787

It was ignoring --workdir.

It is interesting that it is complaining about a race condition in go test -race, specifically here:

      /Users/adeitcher/Documents/Development/go/src/github.com/chainguard-dev/apko/internal/cli/build.go:266 +0x264

That line is part of:

	for _, arch := range archs {
...
		errg.Go(func() error {
...
			pkgs[arch] = installed    // <--- the line with the race condition

I guess it is theoretically possibly if the same arch appears twice in archs, but we already ensure it is unique in types.ParseArchitectures(archstrs). So while it is theoretically possible, it never can happen.

I guess we can put a lock on it, just to ensure this doesn't happen. 🤷‍♂️

That should fix it.

It is happening now.
