[Pkg-bluetooth-maintainers] Bug#390035: /etc/bluetooth/hcid.conf contains pins too

[Mikko Rapeli]

and is readable by all. Unless all users really need to know the pins
for incoming connections, it should be readable and writable by root
only instead of:

# ls -l /etc/bluetooth/hcid.conf
-rw-r--r-- 1 root root 1230 Sep 21 10:38 /etc/bluetooth/hcid.conf
