bitbake: data: Evaluate the value of export/unexport/network flags

Currently the export/unexport/network flags are acted on only by presence
or lack of in the data store. This is deliberate due to performance reasons
since a given recipe shell task might export ~80-90 variables and this means
expanding flags for every one of them.

This does catch users unaware since values which expand to nothing don't work
e.g. ${@""} and setting values to "0" wouldn't work either.

The downside to this patch is slow down in parsing speed of around 4%.

The network flag is easier to change and doesn't affect performance, it was
made to operate the same as export/unexport for consitency reasons.
