[libvirt] [PATCH 1/4] examples: Properly include getopt.h

[Michal Privoznik]

In the admin/logging.c example, the getopt() function is used but
without proper #include. It relies on unistd.h to subsequently
include getopt.h. This is not necessarily always the case.
Also, opterr is not needed and actually not used anywhere else in
our code.
