rumpnet: Add device translator for (Intel) NICsHEADv0.9.git20250801master

This adds a working rump driver for /dev/wmX cards,
which are Intel i8254x Gigabit Ethernet devices.
(See man.netbsd.org for "wm(4)")
This should be easily extended to support other NICs
by contributing some makefile foo to netbsd/rump.

TESTED:
  - On UP+apic it works 100% with hurd-i386.
  - On SMP it also works 100% with hurd-i386.

Example usage:
  settrans -fgap /dev/rumpnet /hurd/rumpnet
  settrans -fgap /dev/wm0 /hurd/devnode -M /dev/rumpnet wm0
  settrans -fgap /servers/socket/2 /hurd/pfinet -i /dev/wm0
  ifup /dev/wm0

TODO: check tcpdump support

Requires latest master of librump for nofifofs dynamic lib.
