Subject: [PATCH 1/2] Survive VPATH build without w on source tree.

A couple tests pass log options to pgbench, with a bare filename
for --log-prefix, so it would be created in the current directory.
In a VPATH build, inconveniently, the Makefile chdirs into the
original source tree before running this, and if the build user has
no write access there, the tests fail. Chdir back to a nice writable
$TESTDIR/tmp_check to avoid that.
