Do not allow System.load() of external libraries

The greylisting mechanism had a bug that allowed
loading any library using absolute path from java code.

It mistakenly assumed they are needed by greylisted
system library when in fact it is dlopen() call from
libnativeloader.

This patch fixes this problem by checking that the library is in
fact dt_needed and it is not a dlopen call.
