Docker build broken by nsswitch.conf check

[dudleycarr]

NSQ Dockerfile depends on the latest alpine image. When building the NSQ Docker image, it produces the following error:

This error occurs because Alpine now includes /etc/nsswitch.conf in the image:

When the file exists, the condition [ ! -e /etc/nsswith.conf ] will return a status code of 1, failing the RUN and causing the build to fail.

Aside from the fact that Alpine now includes /etc/nsswith.conf, Golang has addressed the lack of /etc/nsswitch.conf since version 1.16. See this commit for reference:
