Fix the following:

ndb_mgm_set_int_parameter
ndb_mgm_set_int64_parameter
ndb_mgm_set_string_parameter


ndb/src/mgmapi/mgmapi.cpp:
  Don't include a ': ' at the end of an args.put() name.
  
  It is likely that the following calls don't work before this checkin:
  ndb_mgm_set_int_parameter
  ndb_mgm_set_int64_parameter
  ndb_mgm_set_string_parameter
  
  luckily nobody was actually calling these.
