crypto: add debug info client emit secureConnect

Currently, when debugging a TLS connection there might be multiple debug
statements 'client emit secureConnect' for the 'secureConnect` event
when using NODE_DEBUG='tls'. While it is possible to step through this
with a debugger that is not always the fastest/easiest to do if
debugging remote code.

This commit adds some additional information to the debug statements to
make it easier to distinguish where the debug statements are coming
from.
