Add boolean value comparison to where tpl function

`where` template function's internal condition check function doesn't
check boolean values and always returns `false` silently.

This adds missing boolean value comparison to the function.
`where Values ".Param.key" true` like clause can be used.

Only "=", "==", "eq", "!=", "<>", "ne" operators are allowed to be used
with a boolean value. If an other operator is passed with it, the
condition check function returns `false` like before.
