kvm-image-minimal: drop remaining ROOTFS_PKGMANAGE_BOOTSTRAP

Commit 4eee02bd6405557c664f91b6079c2f203d48c545 [meta-virtualization:
Drop ROOTFS_PKGMANAGE_BOOTSTRAP] missed this instance so we are
removing this last reference to ROOTFS_PKGMANAGE_BOOTSTRAP now.

The ROOTFS_PKGMANAGE_BOOTSTRAP has been universally removed since
oe-core commit 697804229a172125ce7d3bfc9b343812d6fe3240
[run-postinsts: simplify the logic of whether to install it to
images].
