[truetype] Fix linear metrics of GX variation fonts.
When asking for an unhinted non-default variations,
`linearVertAdvance' is currently the value from the `hmtx' table
instead of the actual value after applying the variation. `HVAR'
support fixes this, but fonts will exist without that table and will
need sane fallback.
* src/truetype/ttgload.c (TT_Process_Simple_Glyph,
load_truetype_glyph): Implement linear advance adjustments if `HVAR'
or `VVAR' tables are missing.
