Subject: build-Add-include-directories-for-all-SDL2_foo-modules

The build system assumed that SDL2 and all the SDL2_foo libraries were
installed with the same ${includedir}, but this is not guaranteed:
we could be using a system copy of SDL2 in conjunction with SDL2_foo
libraries in a non-standard prefix.

This also fixes a build regression with recent Debian SDL2 packages, in
which the SDL2 headers are installed in an architecture-dependent
directory but the SDL2_foo headers are not.
