NaCl SDK: Fixed getos.py crashing due to Git migration.

NaCl SDK: Fixed getos.py crashing due to Git migration.

Was trying to parse a Git commit hash as an int.

getos --check-version no longer compares exact revision numbers, only
major version numbers (because the Git hashes can't directly be
compared, unlike SVN numbers). Added a TODO to compare
Cr-Commit-Position when it becomes available.

Seems ok to me.

What to you think ben?

I pinged Ben but he's not available today. Do we really need him to review it?
(I was hoping to get this in today since it seems urgent, but it's up to you.)
