do not handle errors on mktemp in shell scripts

errors are not defined for mktemp, and the /tmp file
system should be assumed reliable.

if /tmp is *unreliable*, then this is not something that
lbmk either can or should fix; the user clearly has
bigger problems.

manpages for mktemp do not define errors. it is assumed
to be completely reliable.
