build: Switch to non-recursive make

Build logic moves from individual Makefile.am's to include files, which
the main src/Makefile.am includes. This avoids having to manage a gigantic
single Makefile.

TODO: Move the rules from the old Makefile.include to where they actually
belong and nuke the old file.

src/Makefile.qttest.include
