Introduce HOMEBREW_CURL_VERBOSE

When investigating issues, one might want to see exactly what curl is
doing behind the scenes. Setting HOMEBREW_CURL_VERBOSE will cause the
'--verbose' flag to be passed to all invocations of curl.

Prompted by #8992.

Ignore $HOME/.curlrc when invoking curl

Several issues have been caused by conflicts between the options
Homebrew passes to curl and those read from $HOME/.curlrc. Passing '-q'
will force curl to ignore settings in that file.

Suggested in #9027.
