All LuaJIT related LSan warnings were suppressed in the scope of the
commit 985548e4 ("asan: suppress all
LSAN warnings related to LuaJIT"), since all compiler flags tweaks were
enclosed in LuaJIT CMake machinery. As a result of the commit in LuaJIT
submodule tarantool/luajit@a86e376 ("build: introduce LUAJIT_USE_ASAN
option") ASan and LSan support has been finally added to LuaJIT runtime,
so it was decided to remove LSan suppressions for LuaJIT functions.
Unfortunately, it was not so easy as it looked like.

At first, Lua global state is not closed properly at Tarantool instance
exit (see <tarantool_free> in src/main.cc and <tarantool_lua_free> in
src/lua/init.c for more info), so LSan false-positive leaks are detected
(for more info, see #3071). Hence, the original LSan suppression for
lj_BC_FUNCC is returned back (temporarily) until the aforementioned
issue is not resolved.

Furthermore, the internal LuaJIT memory allocator is not instrumented
yet, so to find any memory faults it's worth building LuaJIT with system
provided memory allocator (i.e. enable LUAJIT_USE_SYSMALLOC option).
However, again, since Tarantool doesn't finalize Lua universe the right
way, so running Tarantool testing routine with LUAJIT_USE_SYSMALLOC
enabled generates false-positive LSan leaks. Return back here to enable
LUAJIT_USE_SYSMALLOC, when #3071 is resolved.

Last but not least, the default value of fiber stack size is 512Kb, but
several tests in test/PUC-Rio-Lua-5.1-test suite in LuaJIT submodule
(e.g. some cases with deep recursion in errors.lua or pm.lua) have
already been tweaked according to the limitations mentioned in #5782,
but the crashes still occur while running LuaJIT tests with ASan support
enabled. Experiments once again confirm the notorious quote that "640 Kb
ought to be enough for anybody".

Anyway, LuaJIT tests are added to <test-release-asan> target in .test.mk
and LUAJIT_TEST_ENV is extended with required ASan and LSan options.

Follows up #5878
