for use with a 32 bit JRE.

Rationale:
On an x64 system using a 32 bit jvm Without the 32 bit libwrapper, messages
like this will be shown in wrapper.log with the wrapper in MTN & I2P >= 0.8.7:

-----------------------
 Launching a JVM...
 WrapperManager: Initializing...
 WrapperManager: 
 WrapperManager: WARNING - Unable to load the Wrapper's native library 'libwrapper.so'.
 WrapperManager:           The file is located on the path at the following location but
 WrapperManager:           could not be loaded:
 WrapperManager:             $I2P/lib/libwrapper.so
 WrapperManager:           Please verify that the file is both readable and executable by the
 WrapperManager:           current user and that the file has not been corrupted in any way.
 WrapperManager:           One common cause of this problem is running a 32-bit version
 WrapperManager:           of the Wrapper with a 64-bit version of Java, or vica versa.
 WrapperManager:           This is a 32-bit JVM.
 WrapperManager:           Reported cause:
 WrapperManager:             $I2P/lib/libwrapper.so: $I2P/lib/libwrapper.so: 
                           wrong ELF class: ELFCLASS64 (Possible cause: architecture word width mismatch)
 WrapperManager:           System signals will not be handled correctly.
-----------------------

With libwrapper.so removed, one sees the following:

 WrapperManager: WARNING - Unable to load the Wrapper's native library because none of the
 WrapperManager:           following files:
 WrapperManager:             libwrapper-linux-x86-32.so
 WrapperManager:             libwrapper.so
 WrapperManager:           could be located on the following java.library.path:
 WrapperManager:             $I2P
 WrapperManager:             $I2P/lib
 WrapperManager:           Please see the documentation for the wrapper.java.library.path
 WrapperManager:           configuration property.
 WrapperManager:           System signals will not be handled correctly.
-----------------------

The 32 bit lib names, when installed on an x64 system, will match the alternate
names that the wrapper looks for.
