[PATCH 5/5] lei q: continue remote search if torsocks(1) is missing

[Eric Wong <e@80x24.org>]

torsocks is just one of many ways to get curl to use Tor,
so we'll continue if we can't find torsocks in our PATH
and assume the user has a proxy configured via curlrc,
the command-line, environment variable, or even firewall
rules.
