Update option_survey.sh

[michaeldexter]

Increase image size from 4G to 5G to accommodate current OS. Tested on 14.1-BETA2.

commit subject line should include a brief description of the change, so include e.g. increase image size or increase image size to 5GB. You can update the commit and push the update to the pull request (or if I'm going to land this I can just make the change).

The title "Update option_survey.sh" is courtesy of the GUI and only let me give a description. :-|

Please edit to your liking or even stage your own pull request. I don't need the credit. I just want it to work.

By the way... syncing this with the VM-IMAGE size in /usr/src/release would solve this in the long term as that code gets much more attention than the build option survey.

FYI, builds reach 85% or so.

51 builds are complete, for those who celebrate:

Note on the sync, but beyond the scope of PR landing to do anything about :)
