utils.bbclass: make FILESEXTRAPATHS colon delimited 

Fixes [YOCTO 1102]

Path variables are typically : delimited. White space is allowed in paths, so
is not a good choice for separating paths. Currently utils.bbclass performs the
following:

    extrapaths = (bb.data.getVar("FILESEXTRAPATHS", d, True) or "").split()

This splits FILESEXTRAPATHS on whitespace. It later splits overrides on : and
reassembles them all together as : delimited.

There is only one user of FILESEXTRAPATHS in oe-core (qt4-tools-native, which
uses : anyway) and none in oe.

Change the split() in utils.bbclass to split on : instead of whitespace. When
splitting on a defined string (":") we must be careful to handle the empty
string case which returns [''] instead of [].

Tested building qt4-tools-native and core-image-minimal for surgarbay from
meta-intel with a couple extra layers with FILESEXTRAPATHS modifications added.
