ser2net: filter non-printable characters from custom options

The custom options are designed to carry only scalar options to be
added to the connector line.

This fixes a security issue when newlines are included in custom options
which can be used to add yet another, arbitrary connector lines.

See https://github.com/openwrt/packages/security/advisories/GHSA-w6q2-vr4f-49x3
