config: launch ifmap-server with append to log for logrotate to work right

[Hampapur Ajay]

Logrotation of ifmap-server-console.log is incorrect. After every rotation the new file
does not truncate even though it has below directives. Instead new file has leading zeros (see hexdump)
followed by new messages at the old offset. To fix we need to do below(append instead of write) in
/usr/bin/ifmap-server script.

java -cp ./lib/ -jar ./irond.jar >> /var/log/contrail/ifmap-server-console.log 2>&1
instead of
java -cp ./lib/ -jar ./irond.jar > /var/log/contrail/ifmap-server-console.log 2>&1

config: append to console redirected file of ifmap to work with logrotate

Avoid exclusive lock on file so it can be truncated by logrotate (see
http://unix.stackexchange.com/questions/46549/logrotate-not-truncating-open-file)

Reproduced + verified fix with forced logrotation.

Closes-Bug: #1438452
