Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
g2o could not be built reproducibly.

This is because the generated PDF contained the current date which
can be fixed by exporting FORCE_SOURCE_DATE. I've also included a
fix to ensure that the build is reproducible regardless of the build
path by ensuring the value G2O_SRC_DIR is not set to the current
build path.

Patch attached.
