Update GYP to r881 to pick up:

The new postbuild step in Chromium's
third_party/WebKit/Source/WebCore/WebCore.gyp/WebCore.gyp:webcore_svg
is running before libwebcore_svg.a exists in clobber debug builds.
Explicitly declaring a target's intended output (linkable or static
library) as an input to the postbuild shell script action forces the
postbuild to wait for the link step to complete. Because no outputs are
declared, the postbuild step will still run each time the target is
built, which is the desired behavior.

BUG=none
TEST=Clean Chromium build:
     rm -rf xcodebuild
     build chrome/chrome.xcodeproj:chrome in Debug mode
