t7610: don't use test_config in a subshell

test_config uses test_when_finished to reset the configuration after the
test, but this does not work inside a subshell.  This does not cause a
problem here because the first thing the next test does is to set this
config variable itself, but we are about to add a check that will
complain when test_when_finished is used in a subshell.

In this case, "subdir" not a submodule so test_config has the same
effect when run at the top level and can simply be moved out of the
subshell.
