Fix WIREMOCK_OPTIONS duplicated

Bug: https://github.com/wiremock/wiremock-docker/issues/91

When passing the wiremock options sometimes fail. This is due the WIREMOCK_OPTIONS being duplicated. I've tested it in the entry point.sh adding -x for tracing.

❯ docker run -e WIREMOCK_OPTIONS='--container-threads=100 --verbose' wiremock/wiremock:test-opts
+ '[' '' = '' -o '' = - ']'
+ set -- java -cp '/var/wiremock/lib/*:/var/wiremock/extensions/*' wiremock.Run --container-threads=100 --verbose
+ '[' '' '!=' '' ']'
+ exec java -cp '/var/wiremock/lib/*:/var/wiremock/extensions/*' wiremock.Run --container-threads=100 --verbose --container-threads=100 --verbose

@jerosa thanks for fixing this. You also need to fix in this file as well - https://github.com/wiremock/wiremock-docker/blob/main/alpine/docker-entrypoint.sh
