mktemp: add message for directory not found

Browse source 
Add special handling in `mktemp` for when the directory that will
contain the temporary file is not found. This situation now produces
the message

    mktemp: failed to create file via template 'XXX': No such file or directory

to match the behavior of GNU mktemp.
