Refactor the function to write and run tests of the test-lib.sh output
into two functions.
When this was added back in 565b6fa87b (tests: refactor mechanics of
testing in a sub test-lib, 2012-12-16) there was no reason to do this,
but since we started supporting test arguments in
517cd55fd5 (test-lib: self-test that --verbose works, 2013-06-23)
we've started to write out duplicate tests simply to test different
arguments, now we'll be able to re-use them.
This change doesn't consolidate any of those tests yet, it just makes
it possible to do so. All the changes in t0000-basic.sh are a simple
search-replacement.
Since the _run_sub_test_lib_test_common() function doesn't handle
running the test anymore we can do away with the sub-shell, which was
used to scope an "unset" and "export" shell variables.

Move the "check_sub_test_lib_test()" and its sister functions to a new
lib-subtest.sh.
In the future (not in this series) I'd like to test test-lib's output
in a more targeted and smaller test, and I'll need these functions to
do that.
