tpm: Define EFI_VARIABLE_DATA_TREE as packed
tpm_measure_variable() calculates VarLogSize by adding the size of VarName
and VarData to the size of EFI_VARIABLE_DATA_TREE, and then subtracting
the size of the UnicodeName and VariableData members. This results in a
calculation that is 5 bytes larger than necessary because it doesn't take
in to account the padding of these members. The effect of this is that
shim measures an additional 5 zero bytes when measuring UEFI variables
(at least on 64-bit architectures).
Byte packing EFI_VARIABLE_DATA_TREE fixes this.
