Re-land https://codereview.chromium.org/11642018/: Add a postbuild action for executables built with ASan on Mac OS.

The action will copy the ASan dynamic runtime to the output dir and into every
bundled executable being built.

Unlike the previous change, this one does not touch build/all.gyp, since our target
doesn't need to be built when building 'All'.
