fix: update path handling on talosctl cgroups

nerakhon · smira · commit e0c38e2ae7d0 · 2026-03-06T19:17:38.000+04:00
The call to filepath.join in current code causes breakage when using talosctl on windows due to wrong slash introduced into the embed path. Signed-off-by: Jan Paul <paulj@nerakhon.cz> (cherry picked from commit c8800b4)
