Fix command-line argv handling.

(cherry-picked from commit 9ebebc9b5)

Before the patch, there was a situation where `luaL_newstate` could fail
in main and the `argv[0]` could be used as a progname in `l_message`.
However, `argv[0]` is not guaranteed to be non-NULL, so the segmentation
fault could occur. This patch fixes the issue by using the predefined
name in that case. Moreover, it refactors the `l_message`, so now there
is no need to pass `pname` everywhere.

The patch is tested with the help of the mocking of `luaL_newstate` by
providing an error-injected implementation of it and preloading it. For
preload to work, the LuaJIT must be built with dynamic build mode
enabled. The corresponding flavor is added to the CI.

The <gh-8594-sysprof-ffunc-crash.test.c> inspects internal symbols from
the LuaJIT static library, so it can't be linked for shared build. The
test is disabled for the dynamic build mode.

Since the Linux kernel 5.18-rc1 release, `argv` is forced to a single
empty string if it is empty [1], so the issue is not reproducible on new
kernels. You may inspect the `dmesg` log for the corresponding warning
entrance.
