targets/egl-static: use inline_drm_helper and Automake.inc helpers

Update all three build systems, and add freedreno to the android
build. Pending future work on the ST we can convert egl-static
to provide either static or dynamic access to the pipe-drivers.

There is no functional change with this patch.

v2: Don't add freedreno to android build, drop the wrapper winsys.
