Some minor changes in jcl's

[vargajb]

Proposed changes

• Insert the delimiter '/*' at the end of in-stream data set. This improves readability. More detail

• LOADTBL.jcl: Runstat will be executed if load was successful.

• DB2SETUP.jcl
  Insert missing comma.
  We get this warning without this comma:
  IGW01585W MEMBER R WILL NOT BE COPIED AND RENAMED FROM DBRMLIB
  DUE TO NO-REPLACE

Fixes # (issue)
