- What I did
Fixed a minor issue in the procdockerstatsd script so there is a space between the command name and arguments in the CMD field for PROCESSSTATS entries

- How I did it
minor script fix

- How to verify it
See UT:
Picked a process with arguments from 'ps -ef'
root 20897 8261 0 Mar23 pts/0 00:03:38 /usr/bin/buffermgrd -l /usr/share/sonic/hwsku/pg_profile_lookup.ini
