Eric Sunshine fca965a3bc t/lib-pager: use sane_unset() to avoid breaking &&-chain
This test intentionally breaks the &&-chain following `unset` since it
doesn't know if `unset` will succeed or fail and doesn't want a local
`unset` failure to abort the test overall. We can do better by using
sane_unset() which can be linked into the &&-chain as usual.
