Merge ~lool/git-build-recipe:fetch-pristine-tar-tags into git-build-recipe:master

[Loïc Minier]

https://code.launchpad.net/~lool/+recipe/linux-nvidia-tegra-sidecar-daily is failing with:
fatal: ambiguous argument '60ab15c3d7a8c92ccfe8fa7f1d650f3f292141a0^{tree}': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
fatal: not a valid object name: 60ab15c3d7a8c92ccfe8fa7f1d650f3f292141a0^{tree}

git-build-recipe only fetches some remote branches (and their tags); this extends the logic to fetch more remote tags that could be pristine-tar related

This recipe then fails to build due to other pristine-tar failures, but that's for another pull request

LGTM, +1
Tested on my local machine, the tags needed by pristine-tar are fetched correctly

[Richard Hansen (rhansen)]

I opened an alternative merge request [1] that is the same as this one except:
  - Tags are put in refs/tags/<remote>/* instead of refs/remotes/<remote>/* (to avoid potential name collisions).
  - I added some comments explaining why fetching is done the way it is.
  - I added tests.
