tests: stat-free-color: do not count stat calls before main

* tests/ls/stat-free-color: The system may perform additional stat
calls upon loading (seen on OpenSuSE-11.4).  Count only the number
of stat calls compared to --help.
This also reduces back to "1" the number of expected calls,
effectively reverting part of 2011-06-01 commit, ccf2d9a4.
