rootfs: Ensure run-postinsts is not uninstalled for read-only-rootfs-delayed-postinsts

This patch ensures that pkg_postinst_ontarget task is executed for read only rootfs when
read-only-rootfs-delayed-postinsts is set as IMAGE_FEATURES. The issue was that run-postinsts
could be uninstalled at the end of rootfs construction and that shouldn't happen for
the delayed usecase.

In addition to the fix, a test in meta/lib/oeqa/selftest/cases/overlayfs.py testing
the fix has been implemented.
