Log Message:
PR bin/43639

Redo earlier fix to only prohibit sourcing directories and block special files.
char specials (/dev/tty, /dev/null, ... incl /dev/rwd0a) and fifos are OK.

Posix actually requires that we find only readable files - that is not yet
implemented (doing it sanely, without opening the file twice, is going to
take some more modifications to code elsewhere).
