remove True option to getVar calls

remove True option to getVar calls

getVar() has been defaulting to expanding by default for
a long time (2016), thus remove the True option from
getVar() calls with a regex search and replace.

Search & replace made using the following command:
    sed -e 's|\(d\.getVar \?\)( \?\([^,()]*\), \?True)|\1(\2)|g' \
        -i $(git grep -E 'getVar ?\( ?([^,()]*), ?True\)' \
             | cut -d':' -f1 \
             | sort -u)
