lib/{clean,profile}.mk: robustness improvements

First, let's not do rsync --delete on an unverified target dir again: the lesson was learned during a subway hacking session and I must say that SSDs are frightening fast (even if it was more than a second to realize what happens and terminate the extermination before it got /home, thanks xterm). Second, let's use a variable for common name and make's own realpath function instead of external binary.
