script/setup_host_fedora.sh: remove -p from mkdir

1. There is no need to have -p option in mkdir here, since
   /home/rootless was already created by useradd above.

2. When there is no -p, there is no need to suppress the shellcheck
   warning (which looked like this):

> In script/setup_host_fedora.sh line 21:
> mkdir -m 0700 -p /home/rootless/.ssh
>       ^-- SC2174 (warning): When used with -p, -m only applies to the deepest directory.
