tests/avocado/aspeed: Add TPM TIS I2C test 

Add a new buildroot image based test that attaches a TPM emulator to the
I2C bus and checks for a known PCR0 value for the image that was booted.

Note that this does not tear down swtpm process when qemu execution fails.
The swtpm process will exit when qemu exits if a connection has been
made, but if the test errors before connection then the swtpm process
will still be around.
