If PCRs 8 - 9 are set (i.e. not all-zeros), cal_bootaggr should include
them into the digest.

Registers 8-9 are used to store measurements of the kernel and its
command line (e.g., grub2 bootloader with tpm module enabled). IMA
should include them in the boot aggregate. Registers 8-9 should be
only included in non-SHA1 digests to avoid ambiguity.

IMA is not considering TPM registers 8-9 when calculating the boot
aggregate. When registers 8-9 are used to store measurements of the
kernel and its command line (e.g., grub2 bootloader with tpm module
enabled), IMA should include them in the boot aggregate.
