httpd,telnetd: make default port configurable

BusyBox on Termux can't use ports less than 1024 it's patched to change default port for httpd to 8080 and telnetd to 8023.

https://github.com/termux/termux-packages/blob/master/packages/busybox/0011-networking-telnetd-default-port.patch
https://github.com/termux/termux-packages/blob/master/packages/busybox/0010-networking-httpd-default-port.patch

To avoid such patches we can make port configurable.
