[engine] Improve error messages when run in invalid directory

1. --var flags are not validated until after shac determines that the
   working directory is valid (i.e. contains a shac.star file).
2. If a shac.star file cannot be discovered via git, print the expected
   location of the shac.star file.
3. If a --var flag is specified but no shac.textproto file exists, use a
   slightly different error message to make it more clear that
   shac.textproto doesn't exist yet.
