EvoSuite-generated tests contain local filesystem paths

[wtwhite]

Some EvoSuite-generated test source files contain local filesystem paths built into them, like this:

  public static void setSystemProperties() {

    java.lang.System.setProperties((java.util.Properties) defaultProperties.clone());
    java.lang.System.setProperty("java.io.tmpdir", "/tmp");
    java.lang.System.setProperty("user.home", "/home/wtwhite");
    java.lang.System.setProperty("user.dir", "/home/wtwhite/code/regression-test-generation/find-diff-classes/testgen/mvnc/com/github/oshi/oshi-core/6.4.0");
  }

These could in theory affect test results, though in at least one full test run they did not.
