Patchset #2 shows the diff bumping some checks to 0720 instead of 0700.

The API I'm using --show-sdk-build-version only exists on Xcode 7.2 (I had
assumed Xcode 7 or newer).

It turns out this actually fixes a bug introduced in
https://codereview.chromium.org/1521233002/ 

ProductBuildVersion is not the same as --show-sdk-version -- but 7.2 introduced
--show-sdk-build-version so gyp can still use xcrun and get the speed benefits.

That does mean all gyp-ninja builds built with an Xcode before 7.2 will have the
wrong DTSDKBuild (mac/iOS) and DTPlatformBuild (iOS only) values, but it's
unclear if this matters.

Patchset #3 is a small optimization.

PTAL!

Lgtm!
