Fix GenerateIndex for gsutil directories by stripping colon off directory names.

Fix GenerateIndex for gsutil directories by stripping colon off directory names.

The gsutil ls -L will recursively list the contents of a directory.
Subdirectories are listed with a ':' after them like this: 'subdir/:' with their
contents listed under it. When recursing gsutil will fail on directories that
end with '/:'. This CL strips the colon from that output.

Also looked into:
gsutil ls -r (and -R) dir: still puts the colon at the end
gsutil ls -L dir/** (for flat listing): does not list sub directories at all;
 only shows the files.

File gsd_generate_index.py (right):

https://codereview.chromium.org/11348025/diff/1/gsd_generate_index.py#newcode174
gsd_generate_index.py:174: objects = map(strip_colon, objects)
use lambda fun or else list comprehension:

objects = [path.rstrip(':') for path in objects]
