add --without-tensorflow to CONFIGURE_ARGS

By default tesseract configure checks for tensorflow.  Tensorflow installed
from port breaks the build of tesseract, see error messages below.  The fault
is in the tensorflow port, though I'm not sure how to fix that.  For tesseract
to build, it's enough to patch the Makefile and add
CONFIGURE_ARGS+=--without-tensorflow
