Subject: bitbake: Add tests to cover BB_FETCH_PREMIRRORONLY functionality

Basic test to cover functionality of BB_FETCH_PREMIRRORONLY using
local git repository. Local repository has been chosen to allow easy
manipulation with the repo to simulate behaviour reported in
[Yocto 13233]

(Bitbake rev: 773e0815ba0c2183afcb169cda525b7625e60e42)
