The legacy network stack sets net_try_count to 1 at the beginning of the
net_loop() function. This is required for net_start_again() to work
properly. Therefore, set the variable accordingly in the do_ping()
function when NET_LWIP=y. This fixes an issue where a ping to an
unreachable destination would run twice on the same network device. For
example with qemu_arm64_lwip_defconfig:
=> dhcp
DHCP client bound to address 10.0.2.15 (3 ms)
=> ping 10.0.0.1
Using virtio-net#32 device
ping failed; host 10.0.0.1 is not alive
Using virtio-net#32 device
ping failed; host 10.0.0.1 is not alive
=> QEMU: Terminated

Update the ping command so that a host name is accepted in addition to
an IP address, provided DNS support is enabled.

Move each command in cmd/net-lwip.c into its own file
(cmd/lwip/${cmd}.c).

Prepare to split the ping command from cmd/net-lwip.c by moving the
implementation from net/lwip/dns.c to cmd/lwip.
