mktemp: fix error msg when suffix has path sep.

Browse source 
Correct the error message when the template argument contains a path
separator in its suffix. Before this commit:

    $ mktemp aXXX/b
    mktemp: too few X's in template 'b'

After this commit:

    $ mktemp aXXX/b
    mktemp: invalid suffix '/b', contains directory separator

This error message is more appropriate and matches the behavior of GNU
mktemp.
