AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK was reversed

[Jim Meyering]

I've just checked in the following change.
It made it so coreutils-5.96 uses the lib/lstat.c wrapper
when it shouldn't (e.g., w/linux) and doesn't when it should.

        * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
        Fix typo introduced with 2006-04-02 change.  It reversed the sense
        of the test.
