tools: add a tool to update our Razer quirks for internal keyboards

openrazer keeps a convenient list of keyboard devices that belong to the
RazerBlade line and thus should be marked as internal by us. Let's
use that one.

This script git clones the current openrazer repo, imports the file we
need and then overwrites our current quirks file with the sorted list of
devices.

For the second part of this to work reliable we need a marker in the
quirks file that marks the start of autogenerated entries.

Heavily influenced by @danryu in !887.
