add ceph fs kernel driver to arm iso

The Minikube ISO for aarch64 did not contain the Ceph Filesystem kernel
driver build parameters present for the x86_64 build. This is critical
for running Rook (https://rook.io) storage on Minikube.

`CONFIG_CEPH_LIB=y` was already present, however `CONFIG_CEPH_FS=m` and
`CONFIG_CEPH_FS_POSIX_ACL=y` (both present in the x86_64 image) were not
present and are added here.
