Jeffrey Finkelstein 35fb4e6ea1 mktemp: include suffix in error message 
Include the suffix in the error message produced by `mktemp` when
there are too few Xs in the template. Before this commit,

    $ mktemp --suffix=X aXX
    mktemp: too few X's in template 'aXX'

After this commit,

    $ mktemp --suffix=X aXX
    mktemp: too few X's in template 'aXXX'

This matches the behavior of GNU `mktemp`.
