Updated zconf.gperf patch to be conditional.

The problem is when compiling with clang/LLVM, so not necessarily
specific to OS X. Offsetof is part of C99 and defined in stddef.h, but
is builtin with gcc. This code will check for a definition and try
including stddef.h if it is not found. As a last resort, offsetof will
be defined. Apologies for the resend. I did not sign off.
