transport-helper: fix TSAN race in transfer_debug()

Currently, transfer_debug() lazily initializes a static variable based
on GIT_TRANSLOOP_DEBUG. Since the function may be called from multiple
worker threads, this initialization is racy and is therefore suppressed
in .tsan-suppressions.

Initialize the variable in bidirectional_transfer_loop() before any
worker threads or processes are created. This patch removes the race and
allows dropping the corresponding TSAN suppression.
