Title: Ensure tests pass with a SOCKS proxy configured

HTTP::Tiny uses "ALL_PROXY" and "all_proxy" from the environment to
configure which proxy it uses. This change makes tests pass on a system
with these values set.

HTTP::Tiny throws an exception if it has a value of 0 or the empty
string for these environment variables, so always set them to the
undefined value.
