[Pkg-javascript-devel] Sinon update

[Xavier]

Hi,

to update node-sinon, I propose this way:

 - embed needed @sinonjs/* and nise (sinon has been split)
 - embed bane and just-extend
 - update node-lolex:
   - remove bane (embedded in debian/ for test only)
   - disable test during build (it requires updated sinon)
   - enable test only during autopkgtest

After, each time a @sinonjs/* module will be required for another
package, instead of building a separate package, we will embed it in
node-sinon.

Looks good ?
