[PATCH app-xscope] Retry _X11TransConnect on TRANS_TRY_CONNECT_AGAIN

[Jeff Smith]

Reading through Xtranssock.c reveals that when _X11TransConnect returns the
value TRANS_TRY_CONNECT_AGAIN, it turns off the abstract socket flag, so
that attempting _X11TransConnect might succeed the second time where it
failed the first time.

Now xscope will attempt the connection a second time when it receives the
TRANS_TRY_CONNECT_AGAIN return value on the first connection attempt.
