fts.c: Don't include fcntl--.h twice.

[Jim Meyering]

As Ralf pointed out, module-check reports a lot of oddities.
This fixes one of them.

FWIW, fts.c doesn't really care about _LIBC anymore, since
I've resolved to rename the functions/macros (maybe to nfts, etc).
That's because with the ABI changes, there's no hope of merging
gnulib-fts changes back into glibc.

        * lib/fts.c [!_LGPL_PACKAGE]: Don't include fcntl--.h twice.
        It's already included if !_LIBC.
