finddeps: suppress error messages for unreadable directories

If the find command cannot descend into a directory in order to search
for a PKGBUILD, it is likely a "$pkgdir" which makepkg sets as
unreadable. As far as finddeps is concerned, this error message is not
needed.

Also convert to using null-delimited paths on general principle to
prevent read from splitting on odd paths.
