Noissue - Use sets in build.py were appropriate

The relevant changes are #5939 (in order to properly synchronize translations), #5895 (preventing undesired output on automation servers), #5857 (resolves npm dependencies if they previously failed) and #5856 (prevents the creation of a npm-version dependent package-lock.json).

What to change

• Change the buildtools dependency to match the respective revision, after #5913 has landed.

hg	git

• Make sure to include the newer version of ensure_dependencies.py

Hints for testers

When trying to build a package in adblockpluschrome, you might have to clean up buidtools in adblockplusui (e.g. delete the folders) - further information can be found in #5856.
