babl: adjust default BABL_TOLERANCE

This as a start of fixing issue #49, lower precision code gets generated
on AMD EPYC, due to use of rcpps to get a reciprocal - which has lower
precision on AMD EPYC. The conversions with AMD EPYC gets included with
a small margin - so we should not be shedding many other fast conversions
due to this.
