modify DKMS configuration file /etc/dkms/framework.conf 
Lower parallel compilation jobs to 1 if less than 2 GB RAM to avoid freezing of virtual machines.

`parallel_jobs=1`

This does not necessarily belong into security-misc, however likely
security-misc will need to modify `/etc/dkms/framework.conf` in the future to
enable kernel module signing.

userspace utilities in order to function properly.

simplify disabling of SUID Disabler and Permission Hardener whitelist 
split `/etc/permission-hardening.d/30_default.conf` into multiple files

`/etc/permission-hardening.d/40_default_whitelist_[...].conf`

therefore make it easier to delete any whitelisted SUID binaries
