automake cleanup: renamed inttypes.h

- In "includes", inttypes.h was cluttering the system's one. This caused
  random build errors on some systems/in some conditions. Renaming it.
- Add emergency defs of PRI*64 headers when int_types.h does not define
  them (which, unfortunately, can happen on some systems).
