It is caused that SecurityException happens in both `File::canWrite` and `Path::toRealPath`. We should fall-through with empty path because the path will be evaluated when emergency dump happens.

I've created this PR:

JDK-8275436 [BACKOUT] JDK-8271949 dumppath in -XX:FlightRecorderOptions does not affect
https://github.com/openjdk/jdk/pull/5994

for doing a [BACKOUT] of the fix that caused these failures.
