[Buildroot] [PATCH 1/2] package/wlroots: change mesa3d dependency to virtual libegl/libgles

[Gilles Talis <gilles.talis@gmail.com>]

From: Julien Olivain <ju.o@free.fr>

Since commits:
https://github.com/swaywm/wlroots/commit/c2288a7b88240e4377bfc1c67b44efb58f704a42
https://github.com/swaywm/wlroots/commit/e18599b05e0f0cbeba11adbd489e801285470eab

Mesa dependency is no longer required. Wlroots is able to run on drivers
that provide EGL and GLES2.0 support (with specific EGL wayland extensions)

This was verified on NXP's i.MX8MMini using imx-gpu-viv driver.
