Stefan Berger 3845a08e0a test: Recreate TPM 1.2 state files with header 
Recreate a TPM 1.2 state file with header.

The state of the TPM 1.2 must be initialized with Startup(ST_CLEAR)
and then saved so that the proper error code appears as a result
when running this test.

The PCR values was originally created by extending PCR 10 with
sha1("test"). This was recreated using this sequence:

s=$(echo -en test | sha1sum | cut -d " " -f1 | sed -n 's/\([a-f0-9]\{2\}\)/\\x\1/pg')
echo -en $s > input
tss1extend  -ha 10 -if input

The volatile state of this TPM instance has

PCR[10] = c78a6e94c73c4d7fc305c8a66bbf1545f4edb7a5  (extend of 'test')

The state is not encrypted.
The value of PCR 10 can be found as follows:

# od -tx1 tpm-00.volatilestate
