Revert "Merge pull request #15476 from JacobEvelyn/master"

This introduces undesirable `Rails.logger` formatters (such as the syslog
formatter) onto a `Logger.new(STDERR)` for the console. The production
logger may be going elsewhere than standard io, so we can't presume to
reuse its formatter.

With syslog, this causes missing newlines in the console, so irb prompts
start at the end of the last log message.

We can work to expose the console formatter in another way to address
the original issue.

This reverts commit 026ce5ddf11c4cda0aae7f33a9266e54117db318, reversing
changes made to 6f0a69c5899ebdc892e2aa23e68e2604fa70fb73.
