feat: custom.d firstboot action

[tswaehn]

I was wondering if we could implement a standardized hook for firstboot actions.

why?:

• actions (ex. enable services) that need to be performed after all the default firstboot is done should be added

suggestions:

• we add by calling predefined script in ./custom.d/firstboot/

this does basically the same as the default firstboot:

cat files/firstboot/10_after_boot.sh >> "${ETC_DIR}/rc.firstboot"
