curl: remove curl-7.26.0_win-proxy.patch

There is no justification why this patch was added, upstream doesn't
want to add such a feature[1], and maintaining feature patches in LO
for bundled externals doesn't make sense.

Also, this doesn't respect the Inet::Settings::ooInetHTTPProxy*
settings from the configuration.

Let's remove it and hope nobody complains.
