getcwd(2): saner logics around prepend_path() call
The only negative value that might get returned by prepend_path() is
-ENAMETOOLONG, and that happens only on overflow. The same goes for
prepend_unreachable(). Overflow is detectable by observing negative
buflen, so we can simplify the control flow around the prepend_path()
call. Expand prepend_unreachable(), while we are at it - that's the
only caller.
