[LTP] [PATCH] getdents: Fix build under glibc 2.30

[Petr Vorel]

glibc commit b8b3d5a14e ("Linux: Move getdents64 to <dirent.h>")
moved the declaration from <unistd.h> to <dirent.h> to match the
location of the declaration in musl.

Thus we need to include both <dirent.h> and <unistd.h> for getdents64().

Using getdents64() declaration requires on both glibc and musl
_GNU_SOURCE definition, thus move it to to getdents.h.

Fixes: 587

Hi,

you might not like moving _GNU_SOURCE definition to the header, I can
add the missing one in getdents01.c instead.

Travis: https://travis-ci.org/pevik/ltp/builds/595021543

Kind regards,
Petr
