Recreate TPM 1.2 state files with similar content but with the state
file header. The older versions of the state files were created before
the header was introduced in v0.1. The goal is to be able to get rid
of code supporting pre-v0.1 files that had no header.
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

Integrity protect the TPM state when it is written in entrypted form.
libtpms state (for TPM1.2) is also integrity protecting the blobs, but
we better determine the integrity of the decrypted data on the layer
above it.
