* override ${SEPB} to build in tree as we're mentioned in seperatebuildir.inc and need to
  get rid of it for this particular case
* various fixes related to GPRS, Network registration, etc.

connman: don't depend on ofono/bluez but let packagegroup do that

We don't need a direct dependency from connman on ofono or bluez as that is something we
have to decide per machine and the best place for this is a packagegroup. ofono gets now
included by the already existing packagegroup-webos-telephony and bluez is already through
package-webos-ports-extended.
