net: prefer /etc/hosts over DNS when no /etc/nsswitch.conf is present

Do not mimic glibc behavior if /etc/nsswitch.conf is missing. This will
will likely be missing on musl libc systems and glibc systems will likely
always have it, resulting in localhost lookup being done over DNS rather
than from /etc/hosts.

Do what makes most sense rather than making any assumption about the
libc.

Fixes #35305
