With this change, `gclient runhooks` creates ninja files by default on Mac.
To build, run `ninja -C out/Release chrome`. The output appears in out/
instead of in xcodebuild/. (This doesn't happen if OS=ios, so it shouldn't
affect chrome/ios development.)
If you need to use xcode for some reason, you can
`export GYP_GENERATORS=xcode` to force xcode project generation.
If you do this, please inform me why.
Bots should automatically pick up the binaries in the new location (out).
If something does break, it should be safe to revert this change, and bots
should then automatically go back to picking up binaries from the old
location (xcodebuild).
