[PATCH 1/9] test-lib: preserve GIT_CURL_VERBOSE from the environment

[Jeff King <peff@peff.net>]

Turning on this variable can be useful when debugging http
tests. It does break a few tests in t5541, but it is not
a variable that the user is likely to have enabled
accidentally.

Not necessary for this series, but I found it helpful.

I took a look at making the tests in t5541 work with it, but it's a
little nasty (we have to separate the curl output from the regular
stderr). Unsetting GIT_CURL_VERBOSE for those tests would also be an
option. Or just dropping this patch is OK with me, too; it's really only
for debugging.
