as we don't have any algorithm:
./src/evmctl ima_boot_aggregate
sh: -c: line 0: syntax error near unexpected token `('
sh: -c: line 0: `tsspcrread -halg (null) -ha 0 -ns 2> /dev/null'
sh: -c: line 0: syntax error near unexpected token `('
sh: -c: line 0: `tsspcrread -halg (null) -ha 0 -ns 2> /dev/null'
errno: No such file or directory (2)
Now it just prints:
errno: No such file or directory (2)
Fixes: dc00c92 ("ima-evm-utils: calculate the per TPM bank
boot_aggregate")

Hi Mimi,
not really sure if this is a best place to handle the problem.
Kind regards,
Petr
