Fix varargs parameter logging in LocationAwareSlf4JLogger (#8834) 

Motivation

As pointed out by @91he in
https://github.com/netty/netty/pull/8595#issuecomment-459181794, there
is a remaining bug in LocationAwareSlf4JLogger following the updates
done in #8595. The logging methods which take a varargs message
parameter array should format using MessageFormatter.arrayFormat rather
than MessageFormatter.format.

Modifications

Change varargs param methods in LocationAwareSlf4JLogger to use
MessageFormatter.arrayFormat and extend unit test to cover these cases.

Results

Correct log output when logging messages with > 2 parameters when using
LocationAwareSlf4JLogger.
