unistd: avoid namespace pollution on non-glibc systems

* lib/unistd.in.h: #define __need_getopt before including <getopt.h>.
This avoids namespace pollution on non-glibc systems, by causing
gnulib unistd.h to behave more like glibc unistd.h.  I also hope
that this fixes a bug on FreeBSD, reported by Mats Erik Andersson in
<http://lists.gnu.org/archive/html/bug-gnulib/2013-02/msg00027.html>.
