Ticket #48254 - CLI db2index fails with usage errors
Bug Description:
1) CLI db2index had an issue in option handling, which accidentally
added '=' at the end of the previous option.
2) if a value of an option includes a white space, e.g., -T "by MCC
ou=People dc=example dc=com", the value was not passed to the program
as a string.
Fix Description:
1) Removed unnecessary '='.
2) Quote $OPTARG which could include a white space, and call ns-slapd
command line vai eval.
