[Libosinfo] [PATCH v2] tools: Fix compilation with Clang 6

[Andrea Bolognani]

Clang 6 doesn't like the way the last item in a GOptionEntry
array is initialized:

  ../../tools/osinfo-install-script.c:87:12: error: missing field
  'short_name' initializer [-Werror,-Wmissing-field-initializers]
      { NULL }
             ^
  1 error generated.
  gmake[2]: *** [Makefile:540: osinfo-install-script.o] Error 1
  gmake[2]: *** Waiting for unfinished jobs....
  ../../tools/osinfo-detect.c:104:12: error: missing field
  'short_name' initializer [-Werror,-Wmissing-field-initializers]
      { NULL }
             ^
  1 error generated.
  gmake[2]: *** [Makefile:540: osinfo-detect.o] Error 1

Fix the issue by using the { 0 } initializer instead.
