[bug#34249] [PATCH] guix package: Avoid spinner at end of output.

[Christopher Baines]

Often guix package will report something like the following when performing
operations, for example:

  guix package -i hello
  ...
  building /gnu/store/wiwqmbi66gcr27dac3qqgrc8imyp1344-profile.drv...
  -117 packages in profile

Now there aren't -117 packages in this profile, it's just the spinner running
in to the output from Guix package. I'm not sure if this is a proper solution
for this issue, but it does work.

* guix/scripts/package.scm (build-and-use-profile): Erase the spinner before
output.
