top: respond to library changes regarding self lookups

Just in case, make the old proc_t used in the before()
function static so valgrind doesn't get his panties in
a bunch over the fact the 'cmd' is now dynamic memory.

[ Shouldn't that function, or an equivalent, also be ]
[ part of our new library's implementation? However, ]
[ is it proper for a brand new library to abnormally ]
[ terminate a calling process with a stderr message? ]
