Commit 124ab1dc0a and 5523ee3459 introduced the assignment of the
group "tty" to /dev/tty* devices in order to support unprivileged
user access to serial devices.
However, due to an improperly rebased commit this feature broke.
This patch restores the lost hunk in hotplug.json file to
re-introduce this feature and also renames the existing "tty" group
to "dialout" as this is the more typical name for such a group
on desktop systems.

Adjust default permissions and ownership of /dev/tty* nodes from
0600/root:root to 0660/root:tty in order to support granting
unprivileged user access when needed.

Small cleanup. I initially though /dev/kmsg was used for dmsg(and journald
on desktops) but this seems not to be the case. dmsg is still accessible
as non-root(gives output) which begs the question what does this do? Some
googling reveals that permissions are set to 600 for some embedded systems
while 644 for others. I can't find any justification for the latter. Might
as well err on the side of caution.

This changes the default permissions for /dev entries to be more similar to
a desktop distro. Taken from the defaults of Arch Linux and Ubuntu. Also
changed some that were nonsensical. For example, all 660 permissions on
desktop distros were of the form root:x where x is something other than
root. As such, 660 is useless for LEDE where the specific group is missing.
audio seems to be the only group that isn't.

There are time that programs need to be notified of events from
subsystems that are not enumerated in the .json definition, e.g. QEMU
guest agent by default requires /dev/virtio-ports/org.qemu.guest_agent.0
which is a symlink to /dev/vportMpN from virtio-ports subsystem.

Without this patch, /etc/hotplug.d/tty/30-3g won't be called when you insert or remove a USB-serial cellular modem.
