Use quicklisp release of qmynd and improve source dependencies.

As seen in #64 it's no longer necessary anymore to use a local clone of
qmynd to be able to compile pgloader: simplify the Makefile accordingly.

In passing, add source level dependencies so that if you edit any source
lisp file the binary will get automatically rebuilt by `make`.
