Not work on ruby 3.1 x64-mingw-ucrt

[kubo]

A bug report was filed at the ruby issue tracker. I think that it is an issue of this repository.
https://bugs.ruby-lang.org/issues/18472

The following code tries to load the ruby dll in the ruby bin directory. However it doesn't work on ruby 3.1 x64 distributed by rubyinstaller.org. That's because the dll name is x64-ucrt-ruby310.dll and doesn't match *msvcr*ruby*.dll.

serverengine/lib/serverengine/winsock.rb

Lines 104 to 110 in 4d6dbd3

	ruby_bin_path_buf = Fiddle::Pointer.malloc(1000)
	GetModuleFileNameA(0, ruby_bin_path_buf, ruby_bin_path_buf.size)
	ruby_bin_path = ruby_bin_path_buf.to_s.gsub(/\\/, '/')
	ruby_dll_paths = File.dirname(ruby_bin_path) + '/*msvcr*ruby*.dll'
	ruby_dll_path = Dir.glob(ruby_dll_paths).first
	dlload ruby_dll_path

I think that it will be fixed by the following code:

    require 'rbconfig'
    dlload RbConfig::CONFIG['LIBRUBY_SO']

Well, I checked that a small script including the above code and extern "int rb_w32_map_errno(int)" worked fine but I have not tested it inside of serverengine. I'm not a user of serverengine.

Thanks for your report! I'll check it.
