[Plugin] Fix exception when calling os.makedirs

When calling get_cmd_output_path() to create a directory
via the plugin hpssm, sos threw the following exception:

Traceback (most recent call last):
  File "/root/sos/sos/report/__init__.py", line 1224, in setup
    plug.setup()
  File "/root/sos/sos/report/plugins/hpssm.py", line 67, in setup
    logpath = self.get_cmd_output_path()
              ^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/root/sos/sos/report/plugins/__init__.py", line 2168,
	in get_cmd_output_path
    os.makedirs(cmd_output_path)
  File "<frozen os>", line 225, in makedirs
FileExistsError: [Errno 17] File exists:
'/var/tmp/sos.1gdy83zb/sosreport-localhost-vbwfnpn/sos_commands/hpssm'

This was happening because the directory 'hpssm' was already created.
With this change we avoid any race where we call os.makedirs() after
we have already created the plugin directory.

Closes: RHBZ #2216608
