You need to add "kpse.set_program_name" before the "require" call to
initialize the kpathsea Lua module searchers:

diff --git a/texmf-dist/scripts/expltools/explcheck.lua b/texmf-dist/scripts/expltools/explcheck.lua
index f2b1cfa..dbc41c6 100755
--- a/texmf-dist/scripts/expltools/explcheck.lua

 #!/usr/bin/env texlua
 -- A command-line interface for the static analyzer explcheck.
+kpse.set_program_name("texlua", "explcheck")
 require("explcheck-cli")
