Fix asan for jl_precompile_toplevel_module (JuliaLang#43885)

PR JuliaLang#43793 passed the buildkite test but the logs for JuliaLang#43881 show an address sanitzer failure. Removing jl_precompile_toplevel_module from jl_exported_data.inc fixes the error. For good measure, set it to NULL at the point of definition, even though it gets nulled during initialization.
