build: move CPPFLAGS after source directory includes.

In [1] Ryan Schmidt reported a problem on macports [2] with notmuch
finding an existing installed version of notmuch.h during the build.

This is a partial fix; the user might also specify -I in CFLAGS.

[1]: id:7851CAB5-4556-4931-A0A2-37003E56C927@ryandesign.com

[2]: The problem does not arise when notmuch.h is installed into a
"system" include path that the compiler searches by default.
