Revert "Small fix in CPDF_TrueTypeFont load"
This reverts commit dde95d8be9bc2817e34429fc38ee6d89d6d5ab75.
Reason for revert: the test added is flaky
Original change's description:
> Small fix in CPDF_TrueTypeFont load
>
> The ToUnicode map should not be ignored when it exists. Doing so can cause a
> charcode to be assigned an incorrect glyph index, and will result in garbled
> text.
>
> Bug: chromium:665467
