[unity-scopes] Do not break when sourcing the PKGBUILD
[build-in-chroot.sh] Changelog:

* Download sources in stage 3 (build package) instead of stage 1 (install build
  dependencies). Some packages require a build dependency to generate a portion
  of the PKGBUILD file, which may affect the source list.
* Skip integrity checks in stage 1 because not all sources will exist.
[unity-scopes] Add dependencies so that the package can build in a chroot
Merge remote-tracking branch 'upstream/master'
