mlocate indexes swift objects

[Bjoern]

Apparently we just discovered that mlocate indexes swift object and that can be really bad for disk IO even system stability overall.

root@r1-z3-swiftstorage002:~# lsof /srv/node/disk25
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
updatedb. 303649 root cwd DIR 65,128 4096 3221226269 /srv/node/disk25/objects/107639
updatedb. 303649 root 11r DIR 65,128 50 32 /srv/node/disk25
updatedb. 303649 root 12r DIR 65,128 94208 35 /srv/node/disk25/objects

Hence we should add the option --prunefs xfs to updatedb.mlocate (/etc/cron.daily/mlocate)
