[Bug 1769011] [NEW] The signed binary grubx64.efi does not include the tga module

[John Ryan]

Public bug reported:

When secure boot is enabled on an EFI system, it is not possible to
display background images in TGA format because the tga module is not
pre-loaded by the signed grubx64.efi binary and it is not possible to
insmod the module in a secure boot environment.

The jpeg and png modules are pre-loaded and it is possible to display
background images in those formats.

Since the backgrounds in the grub2-splashimages package are distributed
as TGA images I believe this should be considered a bug.
