Duplicates in Create per_profile snippets directories

[btravouillon]

When several profiles share the same snippets name (like partition or custom_post_install), the task creates the directories for each profile.

ok: [cobbler] => (item=Create directory /var/lib/cobbler/snippets/per_profile/partition)
ok: [cobbler] => (item=Create directory /var/lib/cobbler/snippets/per_profile/custom_post_install)
ok: [cobbler] => (item=Create directory /var/lib/cobbler/snippets/per_profile/partition)
ok: [cobbler] => (item=Create directory /var/lib/cobbler/snippets/per_profile/custom_post_install)
ok: [cobbler] => (item=Create directory /var/lib/cobbler/snippets/per_profile/partition)
ok: [cobbler] => (item=Create directory /var/lib/cobbler/snippets/per_profile/custom_post_install)
ok: [cobbler] => (item=Create directory /var/lib/cobbler/snippets/per_profile/partition)
ok: [cobbler] => (item=Create directory /var/lib/cobbler/snippets/per_profile/custom_post_install)
ok: [cobbler] => (item=Create directory /var/lib/cobbler/snippets/per_profile/partition)

ok: [cobbler] => (item=Create directory /var/lib/cobbler/snippets/per_profile/partition)
ok: [cobbler] => (item=Create directory /var/lib/cobbler/snippets/per_profile/custom_post_install)

	- name: Create per_profile snippets directories
	ansible.builtin.file:
	path: "/var/lib/cobbler/snippets/per_profile/{{ item.1.name }}"
	state: directory
	owner: root
	group: root

	loop: "{{ cobbler_profiles | subelements('snippets', skip_missing=True) }}"
	loop_control:

Running the task once per directory is enough.
