Fix two small bugs with --help.

- Pass the helpdir to pmix_init_util().
  This will trickle down the pmix_show_help_init(), which will
  be added to the pmix_show_help search path. Otherwise, PMIx
  will have no way to know where the PRTE tools help files
  are.

- Add missing PMIX_ERR_SILENT -> PRTE_ERR_SILENT. This was
  causing the prte command parsing to print an extra line with -h.
