This commit fixes an issue in the qpy dump() function's use_symengine
kwarg. When a user provided a truthy value that wasn't the literal
`Truth` boolean object the generated qpy payload would be corrupted.
That's because the check that assigns the encoding key in the file
header was unecessarily checking for the literal ``True`` object instead
of a object that evaluated to true. This was causing the header to say
it was using a sympy encoding, but then all the checks that were
encoding the data were evaluating true and setting symengine data. This
would cause a failure on reading the qpy payload when the parameter
expressions were parsed as it would try to load the binary symengine
encoding with the sympy parser.
