lib: unconditionally include stddef.h
I've used offsetof() in the previous commit to paper over the security
problems in ospf_api.c. This blows the build on FreeBSD 7.0, missing
offsetof(). Let's add that to zebra's generally used includes.
stddef.h (and offsetof) is defined in C89 section 4.1.5 (and not
deprecated/removed by any later standard). If this causes problems, the
bug report should go against the host OS/compiler...
