fix copying lua/* to luadir

[Freed-Wu]

Fix #2

• Before adding new features and new modules, please go to issues to submit the relevant feature description first.
• Write good commit messages and use the same coding conventions as the rest of the project.
• Please commit code to dev branch and we will merge into master branch in feature
• Ensure your edited codes with four spaces instead of TAB.

---

• 增加新特性和新模块之前，请先到issues提交相关特性说明，经过讨论评估确认后，再进行相应的代码提交，避免做无用工作。
• 编写友好可读的提交信息，并使用与工程代码相同的代码规范，代码请用4个空格字符代替tab缩进。
• 请提交代码到dev分支，如果通过，我们会在特定时间合并到master分支上。
• 为了规范化提交日志的格式，commit消息，不要用中文，请用英文描述。

luarock install failed, but I don't know why.

[Freed-Wu]

BTW, if rename src/xmake.lua to lua/luarocks/build/xmake.lua, the modules can be omitted from

build = {
    type = "builtin",
    modules = {
        ["luarocks.build.xmake"] = "src/xmake.lua"
    },
    copy_directories = {}
}

to

build = {
    type = "builtin",
}

And seperate update *.yml to another PR may be clearer?

Error: Failed cloning git repository.

Looks network failure?

[Freed-Wu]

There are no any tag about example https://github.com/Freed-Wu/luarocks-build-xmake/blob/lua/rockspecs/example1-1.0-1.rockspec#L5

Whatever, the CI error is unrelated to this PR. I advise to open another issue to solve it.

[Freed-Wu]

Any other problem?

[waruqi]

Sorry, I forgot it, I will try fix ci in these days.

[waruqi]

I have fixed it, but it need xmake dev version.

[Freed-Wu]

Can you publish a version after merge this PR in luarocks? 1.3-3 are still before this PR.

[waruqi]

try 1.4?
