Update goptlib to v1.1.0

Tor Browser currently includes version 0.5. legacy/trac#32056 (moved) is caused by a bug that was fixed in goptlib 0.7. Here is a patch to upgrade to the latest v1.1.0.

Here is the diff in goptlib. The most notable change is that it uses SOCKS 5 since version 0.6, not SOCKS 4a. https://gitweb.torproject.org/pluggable-transports/goptlib.git/diff/?id=v1.1.0&id2=0.5
