Bug#1029845: harfbuzz: non-distributable font included in source

[James Addison]

Source: harfbuzz
Followup-For: Bug #1029845

Based on the previous: I think that the font was probably accidentally
committed to source control while testing a fix for the issue reported on
GitHub - and so following upstream's removal of the font seems to make sense,
given that there doesn't appear to be any explicit public permission provided
by the owner/successors of the license on the Debian mailing lists.
