efi_loader: Fix spec ID event creation

TCG EFI Protocol Specification defines the number_of_algorithms
field in spec ID event to be equal to the number of active
algorithms supported by the TPM device. In current implementation,
this field is populated with the count of all algorithms supported
by the TPM which leads to incorrect spec ID event creation.

Similarly, the algorithm array in spec ID event should be a variable
length array with length being equal to the number_of_algorithms field.
In current implementation this is defined as a fixed length array
which has been fixed.
