Update SysV parameter configuration documentation for FreeBSD.
FreeBSD hasn't made any use of kern.ipc.semmap since 1.1, and newer
releases reject attempts to set it altogether; so stop recommending
that it be adjusted. Per bug #11161.
Back-patch to all supported branches. Before 9.3, also incorporate
commit 7a42dff47, which touches the same text and for some reason
was not back-patched at the time.
