integrity-image-minimal: Fix IMAGE_INSTALL

Append to IMAGE_INSTALL rather than directly setting the variable
and does it after inheriting core-image.bbclass because in it
IMAGE_INSTALL is set with a default value CORE_IMAGE_BASE_INSTALL.

Variable CORE_IMAGE_BASE_INSTALL includes CORE_IMAGE_EXTRA_INSTALL
so the change allows adding auditd to CORE_IMAGE_EXTRA_INSTALL as
per the instructions in meta-integrity/README.md.
