cbcollect is leaving behind 'kv_trace.json & systemd_journal.gz' files under /tmp dir

Steps:

• Initialize a single node cluster
• Load sample-bucket
• Start cbcollect from the command line using,

  $ /opt/couchbase/bin/cbcollect_info /tmp/test.zip

Observation:

After cbcollect is completed successfully, seeing a random tmp dir "/tmp/tmpziovxbeq" with ~ 11MB of size on each collect

# ls -l /tmp/tmpziovxbeq/

total 10180

-rw-r--r-- 1 root root 8252626 Jan  9 05:45 kv_trace.json

-rw-r--r-- 1 root root 2170555 Jan  9 05:44 systemd_journal.gz

Due to this most of the VMs are hitting the disk full issue in consecutive runs with cbcollect

Expected behavior:

This "tmp{[0-9a-z])" dir should be removed from /tmp after cbcollect command is complete
