Add build dirs to gitignore

[G07cha]

Small improvement that allows to forget about deleting build directories before committing all files for example.

Hello @G07cha, thank you for the PR.

Could you please remove build/ from the .gitignore? We are aware it's a bad practice, but we use that mechanism intensively to run applications with JS instead of CS.

• One reason to run JS instead of CS within the platform is that running node applications with CS implies a memory usage overhead.
• One reason not to build during deployment (when the app is installed) is that it's also costing resources on the Cozy.

In before we find a proper alternative, we are going to keep it versioned.

Thank you, Joseph.
