[truetype] Make trickyness checks depend on TT_USE_BYTECODE_INTERPRETER.

Based on a patch from metarutaiga (MR !106).

* src/truetype/ttobjs.c (tt_skip_pdffont_random_tag,
tt_check_trickyness_family, tt_synth_sfnt_checksum, tt_get_sfnt_checksum,
tt_check_trickyness_sfnt_ids, tt_check_trickyness): Put functions into a
`TT_USE_BYTECODE_INTERPRETER` block.
(tt_face_init): Put trickyness checks into a `TT_USE_BYTECODE_INTERPRETER`
block.

Fixes #1111.
