mesa: loosen small matrix determinant check
When computing a matrix inverse, if the determinant is too small we could hit
a divide by zero. There's a check to prevent this (we basically give up on
computing the inverse and return the identity matrix.) This patch loosens
this test to fix a lighting bug reported by Lars Henning Wendt.
v2: use abs(det) to handle negative values
NOTE: This is a candidate for the 8.0 branch.
