What this PR does / why we need it:

When falco runs with kmod/module driver it needs special filesystems to be mounted from the host such /dev and /sys/module/falco. This commit ensures that we mount them in the falco container.

Note that, the /sys/module/falco is now mounted as /sys/module since we do not know which kind of driver will be used. The falco folder exists under /sys/module only when the kernel module is loaded, hence it's not possible to use the /sys/module/falco hostpath when driver.kind is set to auto.
