truss and procfs

[Matthew Dillon]

:truss(1) always looks for procfs in /proc, it also bails out with some not
:very informative error messages if procfs is not mounted.
:http://eirikn.kerneled.com/dragonfly/truss-procfs.diff checks where procfs
:is mounted and if it is not present truss now tells the user what is
:wrong.

    Yow.  Use asprintf/free instead of sprintf/malloc/snprintf/free :-)
