tests: avoid crash when run under gcov

Running ./autobuild.sh failed when gcov is installed, because
commandtest ended up crashing during gcov's getenv() call after
exit() had already started.  I traced this nasty bug back to
a scoping issue present since the test introduction.

* tests/commandtest.c (mymain): Move newenv...
(newenv): ...to a scope that is still useful during exit().
