jitlayers: use std::make_tuple instead of tuple constructor

[benlorenz]

this should be safer for the type deduction and fixes a build error for macos on Yggdrasil (JuliaPackaging/Yggdrasil#9660):

src/jitlayers.cpp:665:54: error: no viable constructor or deduction guide for deduction of template arguments of 'tuple'
  665 |         incompletemodules.insert(std::pair(codeinst, std::tuple(std::move(params), waiting)));

The Yggdrasil environment is a bit special with a rather new clang (version 17) but an old macos sdk and I don't know exactly in which circumstances this triggers. But I think std::make_tuple should be more reliable when the tuple types are not specified.
