Add nvidia drm drivers to initramfs

[13r0ck]

This should add the nvidia drivers to the initramfs for all systems that have the nvidia-driver-515 package installed, and have 120M free of ESP space

1) If this works, https://github.com/pop-os/system76-driver/pull/246 should be closed. Please check that this fixes the affected systems there, oryp6, oryp9, oryp10, mira-b1, and mega-r2 as well as general regression testing. 2) Please also test for a system with less than 120M of free esp, 3) If possible test for OS upgrades. On broken systems like mega-r2, when doing an OS upgrade does the plymouth upgrade screen also break like the plymouth decrypt screen, if so, does this fix that? (on ubuntu and pop)

Should the 120M check be required if the system already has the DRM driver in initramfs?

In that case, this won't do anything anyway, it also checks for if the DRM is already added, and if so does nothing

Ooops, fixed my math

Looks like the new math is working correctly on my special oryp6:
