RFR: JDK-8034769: Move logutil in corba to make/tools

[Erik Joelsson]

Here is another source location cleanup, this time in the corba repo. 
The 6 classes in com/sun/tools/corba/se/logutil are only used as a build 
tool during compilation of the corba repo. These files should be moved 
to the corba/make/tools/src directory so that it's not confused with 
product code.
