typically use "true" or a similar value to enable features. Using
"disable_lua = false" to enable Lua seems odd.

The Qt log output changes in g6a5e90f2 changed the Qt message handler
to use g_log. Lua logging already used g_log. The Qt variant of
funnel logger, which is used by Lua as g_log backend, is currently
using qDebug and this gives recursive calls to g_log and thus an assert.
Rewrite the lua logging to not use g_log.

Fixes Lua on macOS, tested with an out-of-tree build:
WS_BIN_PATH=$PWD/run ../wireshark/test/test.sh -s wslua
Previously programs that were ran from the build directory would load
data files (radius/, diameter/, init.lua) from the source directory.
Then in the case of Lua, files were loaded from the program directory
($BUILDDIR/run/init.lua on Linux) or source directory
(sSOURCEDIR/epan/wslua/console.lua).
On macOS, this does not work for Lua since files are installed into
$BUILDDIR/run/Wireshark.app/Contents/Resources/share/wireshark/init.lua
instead. Since CMake always copies data files (radius, console.lua,
etc.) into the build directory, make get_datafile_dir() return this
"run" directory instead.

Because call_heur_dissector_direct() didn't set the pinfo->heur_list_name
before calling the heuristic dissector, heur_dissect_lua() would invoke
report_failure(). Unfortunately, calling report_failure() within a dissector
can cause problems because GTK continues invoking timed callbacks while
it displays the modal dialog created by report_failure()... without yet
returning from report_failure(). In such a case, it's possible for
epan_dissect_run() to be called while still within the execution of a
previous call to epan_dissect_run(), which casues an assert since
epan_dissect_run() is not reentrant.
So this commit both fixes the call_heur_dissector_direct() bug as well
as avoids using report_failure() within heur_dissect_lua(). It also
upadtes the dissector.lua script used in the testsuite to match the one
pubshied on the wiki, since that script's heuristic dissector triggered
the bug.
