.dir-locals.el: remove Statoil developer setup specific commands

my emacs always asks me whether I want to apply these settings as it
consideres them unsafe. Furthermore, I use a different directory
structure, so these settings are useless to harmful for me.

If you want to keep these settings around, please move them to ~/.emacs

.dir-locals.el
