Update NetBeans project file

From Fu Jie on build-dev ( http://mail.openjdk.java.net/pipermail/build-dev/2018-December/024550.html ):

Hi all,


OpenJDK build with NetBeans failed during the pre-build process.
---

and:

---
Further more, there are too many invalid items in
make/nb_native/nbproject/configurations.xml. For example
This item is invalid since advancedThresholdPolicy.cpp had been removed
from the project.
----------------------------------------------------------------------------
         <item
path="../../src/hotspot/share/runtime/advancedThresholdPolicy.cpp"
               ex="false"
               tool="1"
               flavor2="0">
         </item>
----------------------------------------------------------------------------
---

The reasons Fu Jie gave:

---
The setting that leads to the failure is:
        <preBuildCommand>sh ../configure --with-debug-level=slowdebug
--disable-zip-debug-info</preBuildCommand>

Two pionts were wrong here:
  1) the path of configure script specified was incorrect which should
just be "sh configure" instead of "sh ../configure".
  2) deprecated --disable-zip-debug-info was used which is now an
unrecognized option.
---

and:

---
To fix the issues, make/nb_native/nbproject/configurations.xml needs to
be updated.
