generate-fontconfig: Create entries for all encountered families

[why]
Some (the most basic) Families are not added.

[how]
The used shell array search is string based and can/will fail when we
search for a short string that is present in a array entry as substring.

Use explicit search instead.

[note]
Also remove some debugging output.

Fixes: #918
