[PATCH] correct smtp-ssl-cert-path description

[PATCH] correct smtp-ssl-cert-path description

[Adam Williamson]

The git-send-email documentation was never updated to reflect
the change made in 01645b74 to use the SSL library's default
CA trust store rather than /etc/ssl/certs as a hardcoded
default CApath. This corrects that, and also tweaks the rest
of the text a bit to explain more accurately what is required
for a valid CApath / CAfile.
