Fix 'gsutil' self-discovery.
Use 'realpath' instead of 'abspath' for self-discovery. This fixes an
issue where 'gsutil' cannot find its dependencies when it is referenced
through a symbolic link.
Specifically, the symlink was: /b/scripts => /b/build/scripts
'gsutil' was called as:
Because '/b/scripts/slave' resolves to '/b/build/scripts/slave', the three
parent directory operators actually resolve to '/b', but 'os.path.abspath'
blindly resolves them to '/'.
- Signed onto failing bot, made this change, 'gsutil' works.
