Fix shared httpd log tailing for dynamically added vhosts

The entrypoint used 'tail -f /var/log/httpd/*' which expands the glob
at startup. Log files created later (when new vhost configs are added)
were never tailed, so 'docker logs' showed nothing for sites added
after the container started.

Replaced with a loop that re-discovers log files every 60 seconds and
restarts tail to include new ones.
