mce-inject: Add an MCE injection case with the yellow status set

Intel processors with the capability of 'threshold-based error status'
use tracking hardware to monitor corrected errors of certain hardware
components (e.g., CPU caches). If the tracking hardware overflows, a
'yellow' flag will be set in the MCI_STATUS[54:53] to indicate that
the corrected errors of the associated hardware component exceed the
predefined threshold. If so, then the system may need to be scheduled
for servicing within a few weeks.

Add an MCE injection case with the yellow status set to test whether the
events of threshold-based corrected errors are handled by Linux kernel
or/and the user-space tools like mcelog or rasdaemon.
