Enabled tests `luaL_dostring_test`, `luaL_loadbuffer_test`,
`luaL_loadstring_test` and `lua_dump_test` for PUC Rio Lua.
`lua_dump_test` was disabled in the commit 1538871
("tests: disable lua_dump_test") and tests `luaL_loadstring_test`,
`luaL_loadbuffer_test`, `luaL_dostring_test` were disabled
in the commit 81e8428 ("tests: fix test names in blacklist").
