curl: add support for ~/.config/curlrc (#6120)

curl supports several locations for the rc file according to its man
page:

[...]
When curl is invoked, it (unless -q, --disable is used) checks for a
default config file and uses it if found, even when -K, --config is
used. The default config file is checked for in the following places in
this order:

1) "$CURL_HOME/.curlrc"
2) "$XDG_CONFIG_HOME/curlrc" (Added in 7.73.0)
3) "$HOME/.curlrc"
