isl_convex_hull.c: valid_direction: properly normalize valid direction
The original code would only normalize all but one of the coordinates
of the valid direction, possibly resulting in a scaled direction, which
may no longer be valid. Normalize the whole vector, resulting in only
a change of representation and not a change of direction.

isl_convex_hull.c: simplify computation of initial facet constraint
The old implementation was needlessly complicated and apparently
incorrect (witness the extra test case).
The simplified version passes the new test case.
The new test case is based on a bug report for CLooG/isl
by Muthu Manikandan <muthumanikandan@gmail.com>.
