[sanitizer] Fix running sanitizer_set_report_path_test on Android (#9…

…9469)

sanitizer_set_report_path_test outputs the following on an Android
builder [1]:

ERROR: Can't create directory:
/data/local/tmp/Output/var/lib/buildbot/sanitizer-buildbot6/sanitizer-x86_64-linux-android/build/compiler_rt_build_android_arm/test/sanitizer_common/asan-arm-Android/Posix/Output/sanitizer_set_report_path_test.cpp.tmp
Path
/data/local/tmp/Output/var/lib/buildbot/sanitizer-buildbot6/sanitizer-x86_64-linux-android/build/compiler_rt_build_android_arm/test/sanitizer_common/asan-arm-Android/Posix/Output/sanitizer_set_report_path_test.cpp.tmp.report_path/report.24954

The order of messages is reversed. 

The test can use strcmp+assert instead of CHECK for `__sanitizer_get_report_path` output.
