docker files and templates: consider changed pid file path from NGINX 1.27.5

[jngrb]

Proposed changes

Fixing issue #302 caused by nginx/pkg-oss#26 and subsequently #301 by modifying the sed replacement such that they match for the old and the new PID file path (/var/run/nginx.pid and /run/nginx.pid shall be changed to /tmp/nginx.pid)
