The EFI_IMAGE_SECURITY_DATABASE_GUID is used for the image execution
information table (cf. UEFI specification 2.9, 32.5.3.1 Using The Image
Execution Information Table).
The lsefisystab command is used to display installed EFI configuration
tables. Currently it only shows the GUID but not a short text for the
table.
Provide a short text for the EFI_IMAGE_SECURITY_DATABASE_GUID.

This modifies most of the places we do some form of:
X = malloc(Y * Z);
to use calloc(Y, Z) instead.
Among other issues, this fixes:
- allocation of integer overflow in grub_png_decode_image_header()
reported by Chris Coulson,
- allocation of integer overflow in luks_recover_key()
reported by Chris Coulson,
- allocation of integer overflow in grub_lvm_detect()
reported by Chris Coulson.

The device tree may passed by the firmware as UEFI configuration

for the device tree.
