[alpine-aports] [PATCH] main/openrc: use overlayfs instead of unionfs for modloop Export this patch

fixes #5144
---
As with unionfs, has no effect unless overlayfs loaded: ie need to
include modules=overlay,... in kernel command line.  Making this the
default would require a patch to alpine-iso too.
