netconsole: selftests: Move netconsole selftests to separate target

This patch moves netconsole selftests from drivers/net to its own target
in drivers/net/netconsole.

This change helps saving some resources from CI since tests in
drivers/net automatically run against real hardware which are not used
by netconsole tests as they rely solely on netdevsim.

lib_netcons.sh is kept under drivers/net/lib since it is also used by
bonding selftests. Finally, drivers/net config remains unchanged as
netpoll_basic.py requires netconsole (and does leverage real HW testing).
