Description of problem:
The lowercase BE (U+0431, б ) looks incorrect. It looks like Greek lowercase
delta δ. This is related to this change
https://pagure.io/liberation-fonts/c/607af724740a2daf868b4d2b731d58bf1f5b46a...
and bug 657849

While those changes may matter for Serbian, the Macedonian BE in regular fonts
actually looks same as the Russian. ONLY in italic fonts the delta look is
applicable, because italic fonts kinda look like handwriting.

Note that if you open the page for Cyrillic alphabet or the Cyrillic BE on
wikipedia, it states incorrect and uncited info about this, Macedonian and
Serbian shape of BE is different.

Version-Release number of selected component (if applicable):
2.00.1

How reproducible:

Steps to Reproduce:
1. Install harfbuzz and liberation2
2. Run the following commands

cd location/of/fonts
hb-view --language=mk LiberationSerif-Regular.ttf б
hb-view --language=mk LiberationSans-Regular.ttf б
hb-view --language=mk LiberationMono-Regular.ttf б

hb-view --language=mk LiberationSerif-Bold.ttf б
hb-view --language=mk LiberationSans-Bold.ttf б
hb-view --language=mk LiberationMono-Bold.ttf б

Alternative way to trigger is to:
1. Open libeoffice (Liberation Serif is selected by default)
2. Write: б
3. Select that and change the paragraph language to Macedonian.

Actual results:
I see the delta

Expected results:
Should have the standard "six" shape, not "delta" shape

cd location/of/fonts
hb-view --language=en LiberationSerif-Regular.ttf б
hb-view --language=en LiberationSans-Regular.ttf б
hb-view --language=en LiberationMono-Regular.ttf б

hb-view --language=en LiberationSerif-Bold.ttf б
hb-view --language=en LiberationSans-Bold.ttf б
hb-view --language=en LiberationMono-Bold.ttf б
