add RAUC_IMAGE_SIZE as hook variable

[hellow554]

Closes #700

[ejoerns]

Any idea why?

What does a rauc info on the bundle show? Also negative numbers or a proper value?

[ejoerns]

@hellow554 If I see it right, the context of the variable should be the function, thus this should be sufficient for setting the environment. Just to be sure that it is no autofree issue, just leave out the g_autofree for testing.

From a quick look into this, I don't have a clue what is going wrong, yet. The positive number from your first run is the correct size?

[hellow554]

Hmm, what is happening with these tests? The only one I can see so far failing is

https://github.com/rauc/rauc/pull/703/checks?check_run_id=1910777178#step:7:502

but I don't know what that actually means

[ejoerns]

@hellow554 This is a sporadic error we are aware of. Unrelated to your changes.

Would you squash the two commits into one? There is no benefit in keeping them separate I guess.

[hellow554]

Done.
I like to keep commits seperated when discussing about them, so it's easier to track changes. But yes, before actually merging I like to squash them.

Thanks for your help here!
