[Buildroot] [PATCH v7 3/8] package/libepoxy: remove gl/egl dependency

[Joseph Kogut <joseph.kogut@gmail.com>]

Libepoxy is a library for handling OpenGL function pointer management.

It has backends for egl/glx, which may at one point have been mandatory
to enable, but the library now builds with none of the above enabled
features, as seen below.

  libepoxy 1.5.10

      libdir                 : lib
      build.pkg_config_path  : /home/joseph/br-test-pkg/arm-aarch64/host/lib/pkgconfig
      prefix                 : /usr
      strip                  : false
      tests                  : false
      x11                    : false

Removing these dependencies allows for some applications that require it
as a build dependency, but otherwise can run headless or without GL, to
build and function, using other graphics APIs or display pipelines.

Weston, for example, can still use Vulkan and DRM when linked to
libepoxy without GL/EGL/X11 support.
