Fix interpolation tests of transform: perspective().

These tests were testing the behavior with little-enough accuracy that
it was undetected that they were testing for the wrong behavior.
Interpolation rules for perspective() are defined in
https://drafts.csswg.org/css-transforms-2/#interpolation-of-transform-functions
and simplify to interpolating the inverse of the function argument.
