resolvconf: make it work

The current resolvconf does not work. Make it work with the
following changes.
1. Install normalize-resolvconf, which is used by resolvconf.
2. Add dependencies: sed, util-linux-flock.
   util-linux-flock is needed by our busybox does not support '-w'
   by default. sed is needed because we want to avoid package
   QA issue complaining sed is needed by no one provides it.
3. Add a patch to replace 'readlink -m' with 'readlink -l'.
   This could avoid the runtime dependency on coreutils. The replacement
   is safe as /etc always exits in OE's system.
4. Remove allarch inheritage. This is because the above RDEPENDS
   change does not allow this any more. test_sstate_allarch_samesigs
   would fail if we don't do this.

+Subject: [PATCH] avoid using -m option for readlink
+
+Use a more widely used option '-f' instead of '-m' here to
+avoid dependency on coreutils.
+
+Looking at the git history of the resolvconf repo, the '-m'
+is deliberately used. And it wants to depend on coreutils.
+But in case of OE, the existence of /etc is ensured, and busybox
+readlink provides '-f' option, so we can just use '-f'. In this
+way, the coreutils dependency is not necessary any more.
