egl: Soften several HAVE_DRM_PLATFORM to HAVE_LIBDRM

To fix build when libdrm is not found,
commit a594cec7e3ef275c386054127a357110a19dd823 did put several
parts of egl code under #ifdef HAVE_DRM_PLATFORM.

HAVE_DRM_PLATFORM means the egl drm platform is being built.
What should have been used instead is HAVE_LIBDRM.

At a few locations, the HAVE_DRM_PLATFORM introduced
have already been replaced by HAVE_LIBDRM, this patch
replaces the remaining occurences.

This patch makes for example EGL_EXT_image_dma_buf_import
be advertised by egl under x11 when the drm egl platform
is not built, whereas previously it required the drm egl
platform to be built.

the BUILT_SOURCES.

As the config option --with-egl-platform=wayland is not the default, we
won't end up setting the WAYLAND_SCANNER variable, which in turn will
cause some files to not get generated.

fall back to manually searching via AC_PATH_PROG when needed.
