We want the GuestOS to have access to the same fonts as ChromeOS. To
achieve this, on TerminaVM startup we will ask Seneschal to share the
fonts directory with the VM. Tremplin will then share this with the
container.

ChromeOS             VM                    Container
/usr/share/fonts --> /mnt/shared/fonts --> /mnt/chromeos/fonts
