Fix a number of Makefile.third rules

Partially reverts 8c133b0 (from koreader#1679).

The logic behind including them doesn't check out. The targets in question depend on the files that are to be written in those very /include directories. If they fail to be created properly the target fails. Therefore including them in Makefile.third in this manner doesn't make much sense.

I originally thought it was a bit weird but harmless, but as it turns out it's the exact opposite. So yeah, it has to go away ASAP.
