Remove copy error syslog TCP+TLS options example (docker#3097)

SamLR · johndmulhausen · commit 65c3f1befaf9 · 2017-04-28T22:03:39.000Z
The syslog TCP+TLS example suggests that the relevant options are `syslog-tls-ca-cert=syslog-tls-ca-cert=...`, `syslog-tls-cert=syslog-tls-ca-cert=...` and `syslog-tls-key=syslog-tls-ca-cert=...`. This corrects this example.
