lib: Portability to FreeBSD
Various portability fixes for FreeBSD. POSIX requires shm file names to start with a "/" to be portable. lseek(2) can be undefined on POSIX shm, replaced with ftruncate(2). IRMd check on existing lockfile more portable. FreeBSD 11.0 is preferred as it natively supports robust mutexes. Full working LLC implementation pending.
