systemd: network: Add a note about temporary static resolv.conf for the chroot environment

Browse Source 
I still think this is obvious but it seems some people are surprised by
"unknown host" in chroot.  Let's just note it before they propose a
change for every BLFS package of which the build process requires an
Internet connection.

If you want to use <command>systemd-resolved</command> for the
LFS system but you need to access the Internet in the chroot
environment (for example, for building a BLFS package of which the
build process requires an Internet connection), create the
<filename>/etc/resolv.conf</filename> file following the
static configuration below for the chroot environment so the name
resolution will work in the chroot environment. When you exit
the chroot environment, remove it so
<command>systemd-resolved</command> will create the symlink on
boot.
