Add 3 more testcases demonstrating how install -l sr works

The additional testcases use absolute paths for sources and targets,
as the other testcase which tested `-l sr` used flat relative paths in
the same directory.

Please note that these testcases do not test `-l a` -- that's already
addressed in the battery of tests.
