FreeBSD removed CIRCLEQ from sys/queue.h, but Linux libc still exposes it. Provide the historic queue macros for ports that expect the Linux API.

FreeBSD removed CIRCLEQ_* from <sys/queue.h>. glibc still provides them, so Linux-oriented code that includes <sys/queue.h> fails to build on FreeBSD.
Add linuxapi/sys/queue.h in the same style as the other shims: include_next the system header, then define the historic 4.4BSD CIRCLEQ macros when they are absent. Cover CIRCLEQ_HEAD, CIRCLEQ_ENTRY, insert/remove, foreach, and the loop accessors.
Extend tests/smoketest.c so the header is compiled.
Fixes #5
