compat: fixes for header handling with OpenBSD / NetBSD

Handle OpenBSD and NetBSD as FreeBSD / DragonFly are. OpenBSD would need _XOPEN_SOURCE to be set to 700. Its simpler to just not set _XOPEN_SOURCE. CC strbuf.o strbuf.c:645:6: warning: call to undeclared function 'getdelim'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] r = getdelim(&sb->buf, &sb->alloc, term, fp); ^ 1 warning generated.
