RFR: 8273575: memory leak in appendBootClassPath(), paths must be deallocated

[Serguei Spitsyn]

The memory allocated and hold in the paths local variable of function appendBootClassPath() is never deallocated:
    splitPathList(pathList, &count, &paths);
So, it is a memory leak which needs to be fixed.
The fix is to add one line at the end of function: 
    free(paths);
