Fix SOURCEDIR, BUILDDIR and similar when `cd` prints to stdout
Several variables containing directories in `aglsetup.sh` and other scripts use the common one-liner "cd $DIR && pwd -P" to resolve symlinks. Unfortunately, in some cases, `cd` writes the new directory to stdout, e.g. when using multiple search paths. This commit changes the above to "cd $DIR > /dev/null && pwd -P" to make it more robust.
