Subject: [PATCH] github: Fix up malformed /etc/hosts.

For some reason /etc/hosts in GHA now contains a plain text line
like this:

  Note: Don't Delete this file. Also, don't remove this line. ...

This breaks libunbound and makes a series of unit tests to emit
following warning:
  |00001|dns_resolve|WARN|Failed to read etc/hosts: syntax error

Working around this issue by removing a bad line from /etc/hosts
until this fixed properly by GitHub team.

Bug for virtual-environments:
