May as well.

This is a workaround for a Gentoo bug. On Gentoo, "python" is a
launcher which invokes the "active" version of Python. Unfortunately,
it cares about argv[0].

The change causes the invocation to mirror normal execution of a
script from the shell (i.e. argv[0] is set to the name of the
interpreter).

Even without the change, the Gentoo bug can be worked around by
setting GRASS_PYTHON to the specific Python interpreter (e.g. 
"python2.6") rather than the launcher ("python").
