gentoo-overlays: guard with os_family so non-gentoo boxes skip it

Browse source 
The script's body was never wrapped in an os_family template conditional
despite the header claiming it was 'guarded by the chezmoi template
engine'. So topgrade/chezmoi apply would run it on every box and die
with '/var/db/repos/gentoo missing' on arch/debian.

Wrap the body in '{{ if eq .os_family "gentoo" }}' / '{{ else }}' (same
pattern the arch-only chaotic-aur script already uses). On non-gentoo
boxes the rendered script reduces to a single 'skipping' log line.
Also fix two stale comments in the header (filename was 05, not 10).

Verified by rendering with --config override: arch → no-op log line,
gentoo → full body intact, both pass bash -n.
