kernel postmark test has a typo

[garlick]

Problem: tests/kern/t33 fails due to a typo in the test script

t33.diff:> ../../tests/kern/t33: line 13: popd: /tmp/tmp.dagRQES0tH: invalid argument
t33.diff:> popd: usage: popd [-n] [+N | -N]

This fixes it

I suggest this instead to avoid using pushd/popd.
