git-p4: Add simple test case for branch import

Create a basic branch structure in P4 and clone it with git-p4.
Also, make an update on P4 side and check if git-p4 imports it correctly.
The branch structure is created in such a way that git-p4 will fail to import
updates if patch "git-p4: Correct branch base depot path detection" is not
applied.
