[PATCH 2/2] erofs-utils: switch other source files into MIT license

[Gao Xiang <hsiangkao@linux.alibaba.com>]

Let's switch other source files to MIT license since we're absolutely
NOT working on secret rocket science, so licenses should not be
a bottleneck to innovation in the Cloud Native and AI era.

  - most liberofs files in `lib` and `include` directories
    use GPL-2.0+ OR MIT dual license;
 
- - all other files use GPL-2.0+ license, unless

 Relevant licenses can be found in the LICENSES directory.

+This model is selected to emphasize that erofs-utils can be integrated
+into various ecosystems as much as possible.

+However, liberofs should be GPL-2.0+ OR MIT dual license since some
+parts can be shared with the Linux kernel.
