[PATCH 6/7] t5541: move run_with_cmdline_limit to test-lib.sh

[Jeff King <peff@peff.net>]

We use this to test http pushing with a restricted
commandline. Other scripts (like t5551, which does http
fetching) will want to use it, too.

As we discussed a while ago, this is the exact same code that
run_with_limited_stack uses in t7004. However, I think they are
conceptually two different things, and I could imagine a platform where
they have distinct implementations. So I did not refactor t7004 to make
use of this.
