There is no reason to fail a test if the required testing tool is not
present on the system, so skip the test instead of failing it.

Reset "ret" to 0 when a test case fails so that the other test cases
could continue.
Also set the exit status to 1 when encountering a failure to reflect the
test result.

Since grub-protect already supports NV index mode, tpm2_seal_nv() is
replaced with one grub-protect command to simplify the test script.
"tpm2_evictcontrol" is also replaced with "grub-protect --tpm2-evict".

For the tpm2_key_protector module, the TCG2 command submission function
is the only difference between a QEMU instance and grub-emu. To test
TPM2 key unsealing with a QEMU instance, it requires an extra OS image
to invoke grub-protect to seal the LUKS key, rather than a simple
grub-shell rescue CD image. On the other hand, grub-emu can share the
emulated TPM2 device with the host, so that we can seal the LUKS key on
host and test key unsealing with grub-emu.
This test script firstly creates a simple LUKS image to be loaded as a
loopback device in grub-emu. Then an emulated TPM2 device is created by
"swtpm chardev" and PCR 0 and 1 are extended.
There are several test cases in the script to test various settings. Each
test case uses grub-protect or tpm2-tools to seal the LUKS password
with PCR 0 and PCR 1. Then grub-emu is launched to load the LUKS image,
try to mount the image with tpm2_key_protector_init and cryptomount, and
verify the result.
Based on the idea from Michael Chang.
