build: update DirectFB requirements, reduce #ifdefs
Require DirectFB version 0.9.15 instead of 0.9.13.
This simplifies the build system at the cost of requiring a library
version that was released at the end rather than the middle of 2002.

Simplify DirectFB check.

Require DirectFB version 0.9.22.
This allows getting rid of a lot of library version check #ifdeffery.
Release 0.9.22 is from February 2005, so the requirement is reasonable.
