Bug description:
  [ Description ]

  Some ligatures (e.g. "fi") are not displayed in certain fonts, because
  there are two different naming schemes in use in the wild.

  [ Fix ]

  Poppler upstream fixed this by adding a lookup table to fall back to
  the second scheme if necessary.

  [ QA ]

  1. Install tex-gyre
  2. Download https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/1317599/+attachment/4213588/+files/rfa1415_15sep_lect1.pdf
  3. Open the file in evince
  4. Look at "Biometrics: file" on page 3 

  If the "fi" ligature in "file" is not displayed, you have this bug.
  "file" should be displayed normally after it's fixed.

  [ Regression potential ]

  Since this patch implements a fallback only when lookup false, there
  shouldn't be any problems. Still, check all existing PDFs are still
  displayed correctly.

  [ Original report ]

  While there's Bug #1325230 with the same title and the linked PDFs there are working fine here (displaying "fi" correctly) there seems to be still some bug regarding ligatures.
  https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/1325230

  I have some PDFs substituting Helvetica (and others) with TeX Gyre
  Heros and showing no "fi" ligature.  I attached a patch I derived from
  the patch in Bug #1325230 which is working fine. Now it uses Nimbus
  Sans L and the ligatures are fine.
