Remove unneeded WebKit dependency from DEPS.

This dependency was added in r4173 in order to support
the build/android/run_tests.py script.
In http://crrev.com/217588 that script was removed and
build/android/test_runner.py was the preferred script to
launch Android tests with.
Also in http://crrev.com/279515 the dependency on webkitpy
was removed and replaced by copies of the needed files in
build/android/pylib/utils/.
