Fix for CodeCoverage, Instruction and Line results were always 0.00

[FLeven]

My Build was not completing anymore since I activated the Code Coverage, until I removed "[Math]::Truncate"
for the $perc VAR.

I am still able to set and change the threshold for the percentage required to for the build to pass,
this should be the solution to the problem.

Motivation and Context

I want to use the code coverage for my projects

How Has This Been Tested?

I changed the code coverage threshold to fail and pass my builds, and finally the numbers compared as excepted.
