findprog, relocatable-prog: Ignore directories during PATH search.
Reported by Frederick Eaton via Dmitry Goncharov in
<https://lists.gnu.org/archive/html/bug-gnulib/2020-03/msg00003.html>.
The lib/findprog.c implementation of the find_in_path() function was
fixed by this commit.
However, the same issue exists in lib/findprog-in.c, in the
find_in_given_path() (which is what GNU make actually uses), and that
function wasn't updated by the above commit.
Cheers!
