[PATCH] mesa: respect MESA_EGL_NO_X11_HEADERS even with x11 in PACKAGECONFIG

  Subject: mesa: upgrade to 9.2.5

  introduced this do_install_append, but doesn't explain why it doesn't
  respect MESA_EGL_NO_X11_HEADERS flag anymore.

  Not respecting MESA_EGL_NO_X11_HEADERS breaks any build which is using
  qtdeclarative+egl in distribution which has x11 in mesa PACKAGECONFIG
  (e.g. my bitbake world builds).

  The problem is that qtdeclarative is using "None" symbol in
  QSGTexture::Filtering enum, it's possible to rename it in qtdeclarative,
  but it's quite invasive and changes qtdeclarative public APIs, see:
  https://github.com/webOS-ports/meta-webos-ports/commit/31aa85787a7513e279165a25f6f06ea72c576314
  so it was rejected by upstream and I don't want to maintain it in
  meta-qt5 - changing public API in OE build is even worse than if upstream
  does it.

* This change returns MESA_EGL_NO_X11_HEADERS flag so it's relatively
  easy to resolve this conflict in such setups by preventing Xlib.h
  inclusion.
