Fix -Xjitthreshold (for real this time).

My previous "fix" (c89d83e1c05979b68037ad15413fa4460a88e36f) had the
conditions reversed, so you _had_ to use -Xjitthreshold to get a non-zero
threshold, but when you did, you'd get the default instead of what you
asked for!

This was spotted by the jank tests.
