build: Remove obsolete jscsrc overriddes

Also remove redundant 'name', 'repository' and 'licenses' properties
in package.json.

* Repository: Needslessly hardcodes location of itself. Only relevant for npm publish.
* Licenses: Deprecated in favour of 'license'. Needless duplication
  of COPYING file. Only relevant for npm publish.
