fix(Dockerfiles): silence apt-get TTY warnings

mboersma · mboersma · commit e7589cab2a19 · 2015-07-21T15:48:23.000-06:00
The mesos components didn't all set DEBIAN_FRONTEND to
noninteractive, so there were several build warnings about
not finding a TTY. Additionally, some Alpine images still
had a vestigial DEBIAN_FRONTEND statement.
