selftests/ftrace: Fix eventfs ownership testcase to find mount point
Fix eventfs ownership testcase to find mount point if stat -c "%m" failed.
This can happen on the system based on busybox. In this case, this will
try to use the current working directory, which should be a tracefs top
directory (and eventfs is mounted as a part of tracefs.)
If it does not work, the test is skipped as UNRESOLVED because of
the environmental problem.
Fixes: ee9793be08b1 ("tracing/selftests: Add ownership modification tests for eventfs")
