ufc.h not being found by default

[Chaffra Affouda]

It looks like with ufc being installed with setup.py now you have to write

sudo python setup.py install --prefix=/usr.

in order build dolfin because UFCConfig.cmake set UFC_INCLUDE_DIR to /usr/include. It does not work if you do

sudo python setup.py install for UFC

This is not a bug in DOLFIN.
