[OE-core] [PATCH 1/4] packaging: allow globs in CONFFILES

Allow globs in CONFFILES and default CONFFILES to '${sysconfdir}'.
Previously, the CONFFILES variable is a list of config files to be
packaged. However, as these files may come directly from the source
instead of our WORKDIR, it's a very common mistake that we forget to set
this variable in our recipes. This will lead to unexpected behavior
when doing an on-target upgrade. For example, we modify the /etc/login.defs
locally and then do an upgrade. The file will be replaced, which is
obviously not correct.
This patch changes the way of CONFFILES handling. After this change,
the CONFFILES can take the same form as FILES. That means, we don't
have to list a bunch of files for CONFFILES. It will just be expanded
like the FILES variable.
As almost all files under /etc are basically configuration files, we
provide a default value for CONFFILES.
CONNFFILES = "${sysconfdir}"
In this way, we don't need to modify every recipe to set the CONFFILES
variable. Of course, setting CONFFILES in recipes take precedence over
the CONFFILES. For example, if the recipe author decides that package A
should only treat files under ${sysconfdir}/default/ as config files,
he/she can write like this.
CONFFILES_A = "${sysconfdir}/default"
The above situation should not be common. As according to FHS, the /etc
directory is a place for all system related configuration files.
