test-fsync failure on Haiku

[Bruno Haible]

Hi Richard, Jim,

The test-fsync test is failing on Haiku, at line 40. fsync (stdin), when
stdin refers to a terminal input, simply succeeds on this system. I don't
see anything in POSIX which would mandate a failure of this call.

OK to make the test a bit weaker?

        * tests/test-fsync.c: Include <errno.h>.
        (main): Don't require that fsync (0) fails.
