H.J. Lu 98864ed0e0 x86/CET: Fix property note parser [BZ #23467] 
GNU_PROPERTY_X86_FEATURE_1_AND may not be the first property item.  We
need to check each property item until we reach the end of the property
or find GNU_PROPERTY_X86_FEATURE_1_AND.

This patch adds 2 tests.  The first test checks if IBT is enabled and
the second test reads the output from the first test to check if IBT
is is enabled.  The second second test fails if IBT isn't enabled
properly.
