Windows installer: path too long

[drawnword]

When using the Windows installer on Windows 10, at the end of the installation it displays a prompt, which says:
Warning! PATH too long installer unable to modify PATH!

As a result some of the features are not working correctly.
It may be a bug in NSIS:
arangodb/arangodb#1073

I don't have a ready test environment for Windows 10, and simply use CMake->NSIS to create the installer.

The next version release will be made with the latest (for macOS anyway) version of CMake. That may or may not make a difference (the last installer should have been built with pretty recent version also).

I won't be able to really do much debugging on this. If anyone else has suggestions/pull requests I am happy to take a look at them.

Same problem here when I try to install the Client Tools 3.7.11 to Win 10 64bit from the NSIS package.
The installer said: Your PATH environment variable is already too long. The installer is unable to add ArangoDB to it.
Then the installer is stoped without an error code but at approx half of the installation process.
