meta: remove True option to getVar calls (again)

A couple have still been missed in the past despite multiple
attempts at doing so (or simply have re-appeared?).

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)
