Drop -q in ssh-log-wrapper.sh to preserve logs.

scp and sftp like to add -q to the command line passed to ssh which
overrides the LogLevel we set in the config files and suppresses output
to the debug logs so drop any "-q" from the invoked ssh.  In the one
case where we actually want to use -q in the banner test, call the ssh
binary directly bypassing the logging wrapper.
