- Fixes https://github.com/termux/termux-packages/issues/24979
- The package has been orphaned ever since it was introduced in 2022: e96459c7c7
- The package no longer conflicts with `mesa`, `libglvnd-dev` or any other package. It contains one file:
```
~ $ dpkg -L gst-plugins-gl-headers
/.
/data
/data/data
/data/data/com.termux
/data/data/com.termux/files
/data/data/com.termux/files/usr
/data/data/com.termux/files/usr/include
/data/data/com.termux/files/usr/include/GL
/data/data/com.termux/files/usr/include/GL/wglext.h
```
- This file contains large amounts of Windows-specific code and is not found in any other package except for mingw-related packages and highly generalzed frameworks. It is not expected to be necessary for anything on any Linux distro:
```
~ $ apt-file search wglext.h

llvm-mingw-w64-ucrt: /data/data/com.termux/files/usr/opt/llvm-mingw-w64/generic-w64-mingw32/include/GL/wglext.h

qb64: /data/data/com.termux/files/usr/share/qb64/internal/c/parts/core/gl_headers/opengl_org_registery/wglext.h
```
- This file is not found in any `gst-plugins-*` package of any other Linux distribution:

In most cases this code is same, in some cases it is done for libwayland cross building. And it is not obvious what exactly happens here.
This commit makes it more obvious and easier to read.
