catch new untracked and unignored files

- What I did

pkg show-tag reports if a directory tree is dirty, but it misses new untracked files. If a file is in the directory, and is not tracked and also is not in .gitignore, we should treat that is dirty.

- How I did it

Added ls-files with appropriate options.

- How to verify it

I tested it on various scenarios:

• new file in dir - catches it
• new file not in dir - ignores it
• new file in dir but also in gitignore - ignores it

- Description for the changelog

show-tag treats untracked and unignored files as a dirty package.

Can we also adjust contentHash function to handle untracked files? Now they are not covered by hash calculation:

$ ./bin/linuxkit pkg show-tag ../../../pkg/acpid/
linuxkit/acpid:c05a368754f6436b326945dc16135ba547568d8d
$ touch ../../../pkg/acpid/file
$ ./bin/linuxkit pkg show-tag ../../../pkg/acpid/
linuxkit/acpid:c05a368754f6436b326945dc16135ba547568d8d-dirty-e785871
$ echo "test">../../../pkg/acpid/file
$ ./bin/linuxkit pkg show-tag ../../../pkg/acpid/
linuxkit/acpid:c05a368754f6436b326945dc16135ba547568d8d-dirty-e785871

Good idea. Done.

Thank you!
With such changes we will be able to completely get rid of force flag during local development, since now linuxkit (and user) will see that there are changes in source tree regardless of git add command which may come later.
