No specific called "exec(3)", so move primary manpage to a name which

does exist -- execv(3).  Still call this a family but without "Nm".
Adjust Xr in various pages to refer to the precise function used
rather than the family, in most cases the semantics of execve(2) are
being referenced, so change the Xr.
