Don't store git commit in observatory version string

Don't store git commit in observatory version string

The observatory assets tarball would be different every time due to the
version string, which makes it compress to a different size. The size
changes would then move the program data around, making it much more
difficult to determine if dart builds of different revisions are
actually identical.

Google Analytics doesn't need to know the exact version numbers, it will
be fine to say they are bleeding edge builds of a particular version.
