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

[Jim Meyering]

This test started to fail on rawhide, due to some new start-up
code that is run when selinux is enabled.  That code includes
a stat of /selinux:

  statfs("/sys/fs/selinux", 0x7fffbb8f1de0) = -1 ENOENT (No such file or 
directory)
  statfs("/selinux", {f_type=0xf97cff8c, f_bsize=4096, f_blocks=0, f_bfree=0, 
f_bavail=0, f_files=0, f_ffree=0, f_fsid={0, 0}, f_namelen=255, f_frsize=4096}) 
= 0
  statfs("/selinux", {f_type=0xf97cff8c, f_bsize=4096, f_blocks=0, f_bfree=0, 
f_bavail=0, f_files=0, f_ffree=0, f_fsid={0, 0}, f_namelen=255, f_frsize=4096}) 
= 0
  stat("/selinux", {st_mode=S_IFDIR|0755, st_size=0, ...}) = 0

Here's the fix:

Subject: [PATCH] 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.
