Title:
  Installer should copy fontconfig cache to the installed system

Bug description:
  After the installation completes, fontconfig cache files
  (/var/cache/fontconfig) should be copied from the live CD session to
  the just installed system, before reboot.

  The rationale:

  Snapd creates fontconfig cache files (/var/cache/fontconfig) for
  fontconfig cache format v6 and v7 (this is done by snapd to
  significantly reduce startup time for snaps that may use one of the
  two formats). This is a one-time operation that can take as much as
  ~20 seconds; it's performed on the live CD session as it runs snapd,
  but since the newly installed system has empty /var/cache/fontconfig
  after first boot, it needs to be repeated by snapd. This affects first
  boot experience as it has impact on readiness of snapd and snap for
  normal usage. Observed with 19.04 installs.
