[Autodiff] Fixes breaking VJP and pullback inlining tests on Linux

The inlining benefit for VJPs and pullbacks seems to be a bit different on
macos and linux. This difference seems to be arising due to certain
function calls such as, `sin`, `cos` etc. always being inlined on macos
but not on linux.

Until I figure out a better way, I'm modifying these tests to avoid matching
the exact value of the inlining benefit, which causes them to fail on
Linux.
