[yocto] [PATCH V2 1/2] update-rc.d.bbclass: remove preinst and remove -f for postinst

[changqing.li at windriver.com]

From: Changqing Li <changqing.li at windriver.com>

*preinst use "-f remove" to remove any links in the /etc/rcrunlevel.d
  but this will make user cannot keep previous init script link
  after upgrade

  eg: user disable one service before upgrade, after upgrade, service
  could be started since during preinst, all link have been deleted, so
  postinst may create the link to start service.

  remove preinst to keep previous links, so that after upgrade, if any
  link existed for the package, postinst will not create new start/stop
  links.

  (note: patch of support enable/disable function of update-rc.d send
  to yocto mail list today)

*remove -f for postinst, previously, recipe keepalived use remove during
  postinst, so need this -f, but remove in postinst is not proper, recipe
  keepalived have fixed this problem, so remove -f.
