We want almost all cmd subdirectories anyway, and relative to the cost
of the rest of toolchain bootstrapping, copying/rewriting a few extra
source files is way cheaper than the engineering cost of forgetting to
maintain these lists as we split out new packages.
While here, also add cmd/internal/archive (and make it compile with Go
1.4) because it'll be needed in subsequent refactorings anyway; and
skip files starting with # (emacs temporary files) and test files
ending with _test.go.
