tests: avoid git diffstat singular/plural output difference

'git diff --stat' output changed with regard to the amount
of changes/insertions/deletions shown.
In older git versions (1.7.7.6), output was shown as:
2 files changed, 2 insertions(+), 1 deletions(-)
In newer versions, output is shown as:
2 files changed, 2 insertions(+), 1 deletion(-)

This patch uses a regex to handle both cases.
