bitbake.conf: set CONFFILES by default

There are a lot of binary packages have files in /etc/, but only a few
of them have set CONFFILES, 187 packages are not set in a world build.
So treat all the files in /etc/ as CONFILES as Debian does
- Move the file out of /etc/ if it is not a conffile
- If /etc/foo can't be moved out, and is changed during
  runtime, then create a symlink /etc/foo -> /var/foo
