mod-wsgi: allow builds with separated src/build dirs

Unfortunately the use of apxs, which isn't that friendly with
separated src/build dirs, makes things tricky to acheive src/build
separation. With the use of a symlink and a few other minor tweaks we
are able to get this working.

+Subject: [PATCH] build: fix builds that have separated build dir
+
+Setting up the link to the Makefile.in fails since it assumes
+the build is happening in the src directory. As well the Makefile.in
+doesn't make use of VPATH to allow for builds out of the src dir.
