[LTP] [PATCH] chown03: fix the effective user when do cleanup

[Wei Yongjun <yjwei@cn.fujitsu.com>]

The TESTDIR is created by root user, but when we do cleanup, the effective
user had been changed to nobody, so the cleanup will be failed when the
TESTDIR is removed.

  chown03     1  PASS  :  chown() on testfile succeeds, clears setuid/gid bits
  chown03     0  WARN  :  tst_rmdir(): rmobj(/tmp/choYm1VHD) failed: \
    remove(/tmp/choYm1VHD) failed; errno=1: Operation not permitted

This patch fixed the problem by reset the effective user to root.
