toolhead: Remove arbitrary constants controlling junction deviation

When calculating the junction speed between two moves the code checked
for angles greater than 0.999999 or less than -0.999999 to avoid math
issues (sqrt of a negative number and/or divide by zero).  However,
these arbitrary constants could unnecessarily pessimize junction
speeds when angles are close to 180 or 0 degrees.

Change the code to explicitly check for negative numbers during sqrt
and to explicilty check for zero values prior to division.  This
simplifies the code and avoids unnecessarily reducing some junction
speeds.
