tests-subrepo-git: make the "pwned" message output in a stable order
The "pwned" message from this test gets gets sent to stderr, and so may get
emitted in different places from run to run in the rest of mercurial's
output. This patch forces the message to go to a specific file instead,
whose existence and contents we can examine at a stable point in the test's
execution.
