tests: stat-free-color: accommodate stat of /selinux on rawhide

* tests/ls/stat-free-color: This test recently began to fail on
rawhide because dynamic library start-up code now stats "/selinux",
making the total number of calls 2 rather than the prior 1.
Create two more dangling symlinks, so that any erroneous stat-
or lstat-calling code will get at least those three.
