[sheepdog] [PATCH] collie: fill line with spaces correctly in show_progress()

[MORITA Kazutaka]

The current collie doesn't print spaces after the progress bar to the
end of line, so the error message aren't be formated correctly.

For example:

  $ collie vdi check test
   98.0 % [============================>] 196 MB / 200 MB   f
  ixed missing 7c2b2500000011
  100.0 % [=============================] 200 MB / 200 MB
  finish check&repair test

This fixes the problem.
