The main purpose of this patch is to make piglit independent of the
current working directory, so it is possible to package piglit as a RPM
package (with binaries symlinked to /usr/bin, most of the files in
read-only /usr/lib*/piglit directory, and results somewhere else).

So it is now possible to run

$ piglit-run tests/quick-driver.tests /tmp/piglit

and then with this command

$ piglit-summary-html --overwrite /tmp/piglit/results /tmp/piglit/main

generate a report in /tmp/piglit/results/index.html & al.
