[truetype] Reset the IUP-called flags for each subglyph.

This fixes fall-out from 7809007a5b88b15, where the composite
accents were no longer hinted.

* src/truetype/ttgload.c (ttloader_init): Move the IUP-called flag
initialization from here...
* src/truetype/ttinterp.c (TT_Run_Context): ... to here.
