New issue 2526 by post-review fails with new git submodules

What version are you running?
Confirmed on fresh clone of rbtools

What steps will reproduce the problem?
1. Clone a repository with submodules (git >= 1.7.9)
2. Run post-review from a submodule

What is the expected output? What do you see instead?
$ post-review --guess-summary --guess-description --parent=HEAD^
fatal: This operation must be run in a work tree

Please provide any additional information below.
On recent version of git, .git is not stored in the worktree of the submodule anymore but as as a subdirectory of the top project
$ git rev-parse --git-dir
As post-review tries to reach the top directory by chdir to dirname(git_dit)
we end-up into the git directory of the top project so the diff fails.
The idea is to use the --show-toplevel option of git-rev-parse instead (when it exists).
I quickly wrote a patch that fixes the issue for me.
