Fix build breakage on FreeBSD after rL289878/rL289881

Summary: After rL289878/rL289881, the build on FreeBSD is broken, because sanitizer_platform_limits_posix.cc attempts to include <utmp.h> and use `struct utmp`, neither of which are supported anymore on FreeBSD. Fix this by adding `&& !SANITIZER_FREEBSD` in a few places, and stop intercepting utmp functions altogether for FreeBSD.
