CLEANUP: cli/activity: Remove double spacing in set profiling command

It was found that when viewing the help output from the CLI that
"set profiling" had 2 spaces in it, which was pushing it out from
the rest of similar commands.

i.e. it looked like this:
  prepare acl <acl>
  prepare map <acl>
  set  profiling  <what>  {auto|on|off}
  set dynamic-cookie-key backend <bk> <k>
  set map <map> [<key>|#<ref>] <value>
  set maxconn frontend <frontend> <value>

This patch removes all of the double spaces within the command and
unifies them to single spacing, which is what is observed within the
rest of the commands.
