[OE-core] [PATCH] core-image-minimal-initramfs: cause the IMAGE_INSTALL variable to be a limited set

[Saul Wold]

This change causes the IMAGE_INSTALL to be a fixed set of packages
that are know to work and wil not be affected by changes to the
IMAGE_INSTALL variable from the user's local setting.

Since IMAGE_INSTALL is used for all images, but the initramfs needs
to be a well-known sub-set use teh RecipeParsed to finalize it to that
well-known subset.
