generic: drop temporary file option

any program launched with temporary file (as per the spec) argument
(because it does not support %u or %U) should not be responsible for
deleting the file, klauncher already handles that thus the option is
redundant. I don't know how other implemenatations (of program launchers)
do it but I cannot say I care either
