[bug#35446] [PATCH v2 06/24] gnu: calibre: Move font unbundling to after check phase.

[Brendan Tildesley <mail@brendan.scot>]

* gnu/packagse/ebook.scm (calibre): Move font unbundling to after check
  phase. Some of the tests use the font files for various things. It's more
  convenient to just allow the font files to be there than to patche the
  tests.
  We also take the chance to switch from copying the font files in, to having
  font-liberation as an input and symlinking them.
