Convert ConvolverNode tests to testharness

Convert tests to use testharness.  convolver-channels.html was
converted by script but also needed a small manual change because of
testPassed/testFailed, but was otherwise unchanged.

The other tests were converted by hand.

TEST=convolution-mono-mono.html, convolver-channels.html,
convolver-setBuffer-null.html
