kf6-kcrash: remove disguised stub — restore real glRenderer() function

The previous recipe used sed to replace the ENTIRE glRenderer() function
body with  — silently discarding GPU renderer metadata
in crash reports. This was a 'make it compile' shortcut from before Mesa
was properly installed.

Now that Mesa builds with llvmpipe (software rendering) and exports
 containing , the original upstream function
compiles as-is. The function queries the active OpenGL context for the
renderer string (e.g. 'llvmpipe (LLVM 21.0, 256 bits)').

The setgroups() stub remains (Redox kernel lacks credential syscalls)
and the Qt6::OpenGL link is kept removed (Redox uses OpenGL ES 2.0,
not desktop GL — the raw glGetString call comes from mesa/GL/gl.h).
