Fix command to restart healthd
Fix command to restart healthd

The command returned the two processes, healthd and grep:

$ /bin/ps aux | /bin/grep -e '/bin/bash -c healthd'
root      7979  0.0  0.1  56668  2704 ?        Ss   Dec28   0:00 su -s /bin/bash -c healthd healthd
ec2-user  8800  0.0  0.1 110456  2136 pts/0    S+   00:03   0:00 /bin/grep -e /bin/bash -c healthd

killing the ephemeral grep process caused the following error:

2017-12-28 23:18:26,263 [ERROR] Command 02-restart-healthd (sudo /usr/bin/kill $(/bin/ps aux | /bin/grep -e '/bin/bash -c healthd' | /usr/bin/awk '{ print $2 }')) failed

We only need to restart the healthd process.
