Add `"download_fuchsia_deps": False` to the dot-gclient file as this is
for linux, not fuchsia, so the dependencies are not necessary.
Also, change various paths in flutter-engine.mk to ensure that the package
builds correctly.
Remove patch
0005-skip-configuration-dependency-if-unit-tests-are-disa.patch which
is upstream.
Tested with tests.package.test_flutter.TestFlutter.test_run
