Log Message:
-----------
GeanyVC:(Git) Fallback to `git rev-parse` for getting the repo/worktree's top directory

An example setup for worktree:

```
mkdir r1
cd r1

git init
git config user.name testuser
git config user.email testuser@
echo "f1" >> f1
git add f1
git commit -a -m "added f1"

git worktree add ../w1 -b work1
echo "f1:r1" >> f1
git status

cd ../w1
git status
echo "f2" >> f2
git add f2
git commit -a -m "added f2"
echo "f1:w1" >> f1
git status
```

All VC actions should be available for all files in each worktree.
