efi: Correct Macmini DMI match in uefi cert quirk
commit bab715bdaa9ebf28d99a6d1efb2704a30125e96d upstream.
It turns out Apple doesn't capitalise the "mini" in "Macmini" in DMI, which
is inconsistent with other model line names.
Correct the capitalisation of Macmini in the quirk for skipping loading
platform certs on T2 Macs.
Currently users get:
