missing thng with nginx and apache2 optons for proxy system var

Describe the problem:

seems hteres a missing thing when we perform a no - nginx install or using --nginx no, related to #97 and commit 1f8d385cbbc9480b615aed055ebb12251fb27422

hi @myvesta i commented the commit but when we perform install i take care of the log output at the console and found this:

== Adding ns1 and ns2 A records
== FPM pool.d <sub>.<domian>
Error: PROXY_SYSTEM is not enabled
== Adding cron jobs

its my second attepend.. the firt time i used was when was over "vestacp" now with "myvesta" i guess this is cos there's no nginx that acts as proxy-reverse

Steps to Reproduce:

bash vst-install-debian.sh --apache yes --nginx no --phpfpm yes --vsftpd no --proftpd yes --named yes --mysql yes --postgresql no --exim yes --dovecot yes --clamav yes --spamassassin yes --iptables yes --fail2ban yes --quota yes --force no --interactive

and take care of the output

Debian 10, 11
