avoid check failure on glibc 2.22

glibc 2.22 introduces two extra stat() calls per opendir(),
which induces a false failure in a test counting stat() calls.

+Subject: [PATCH] tests: avoid FP of ls/stat-free-color.sh with newer glibc
+
+Since glibc-2.22, specifically commit [0], the opendir() implementation
+implicitly makes an additional stat call thus leading to a FP.
+Seen on openSUSE:Tumbleweed since snapshot 20150821.

+
+* tests/ls/stat-free-color.sh: Change the test to verify that ls(1)
+needs the same number of stat-like calls for a single, empty directory
+argument as for one with a few directory entries (sub-directory,
+regular file, symlink, etc.).
