[OE-core] [PATCH V3 3/4] update-rc.d: use '-f' option in updatercd_postrm

[Chen Qi]

Use '-f' ('--force') option so that while removing packages using deb,
we don't fail because of the following error:

   update-rc.d: $initd/$bn exists during rc.d purge (use -f to force)

Using '-f' option would make this a warning but continue to execute.

   update-rc.d: $initd/$bn exists during rc.d purge (continuing)

We need this option because dpkg package backend have special handling for
configuration files. And if files under /etc/init.d are treated as configuration
files, we will have errors.
