Can we keep it in the virDomainTPMDef structure, so that normal code
computes cancel_path from the normal path at the time of SELinux
labeling, while the testsuite just populates it with a string without
any SELinux labeling?  The testsuite must not be influenced by actual
files on the system running the test.
