provide more includes to Cppcheck

- added (temporary) suppression of Cppcheck `shiftTooManyBits` false positives in `libxrdp/xrdp_mppc_enc.c`
- added (temporary) suppression of Cppcheck `uninitMemberVar` true positives in `ulalaca/ulalaca.cpp` until fixes land downstream
- fix Cppcheck `nullPointerRedundantCheck` in `sesman/chansrv/clipboard.c`
- fix Cppcheck `syntaxError` in `fontutils/mkfv1.c` because it doesn't see the `freetype/fterrors.h` header / removed astyle workaround
