luci-lua-runtime: fix legacy luci-mod-rpc authentication

The split of the former `sysauth` cookie into `sysauth_http` and
`sysauth_https` ones was also imposed upon the RPC module, without
leaving the option to use just `sysauth` in place, so allow this cookie
name again for the legacy RPC logins.

Fixes: #6333
Fixes: e1932592c3 ("luci-base: use different cookie names for HTTP and HTTPS")
