[regress/keys-command.sh]
     Fix some problems with the keys-command test:
      - use string comparison rather than numeric comparison
      - check for existing KEY_COMMAND file and don't clobber if it exists
      - clean up KEY_COMMAND file if we do create it.
      - check that KEY_COMMAND is executable (which it won't be if eg /var/run
        is mounted noexec).
     ok djm.
