Currently ivshmem requires eventfd() which is Linux specific.
Do not and build it unconditionally on every Linux/BSD/Solaris.
This patch indirectly fixes build failure on NetBSD, where these tools
additionally require -lrt for shm_open(3). In future there should be
added support for NetBSD and the linking addressed appropriately.
