apps/tsget: switch WWW::Curl::Easy to Net::Curl::Easy

Minimal module swap: replace WWW::Curl::Easy with Net::Curl::Easy.
Update callback signatures (Net::Curl passes the easy handle as the
first argument), replace error-code-based perform() with eval/die,
and drop cleanup() which Net::Curl does not require.
