Don't map glyphs to Unicode position 0x0E33, i.e. Thai character SARA AM (bug1046314)

*A similar approach as in PR 5705.*

Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1046314.

According to https://dxr.mozilla.org/mozilla-central/source/gfx/harfbuzz/src/hb-ot-shape-complex-thai.cc#270-365, `0x0E33` is treated as a special case (by the font shaping code in Firefox). Hence it seems reasonable to skip it when adjusting the font mapping.
