Alpine Linux support

[dumptruckman]

I am attempting to use this module in conjunction with https://github.com/ljfranklin/terraform-resource in Concourse. However, the tunnel.sh script fails to run due to Error Message: ps: unrecognized option: p. From what I can tell, the ps command in Alpine does not have a -p option. Is it possible to for the script to not do all the process checking stuff and just use some dumb timeouts or something?

Supposed to be fixed in f2f1e7e. Please check.

Thanks for the quick fix! I tested it and it does appear to be working now on Concourse in an Alpine container.
