mesa: Upgrade Mesa for Raspberry Pi 4

Bring Mesa 19.1.6 to meta-agl-bsp/meta-raspberrypi because there
are driver issues with Mesa 18.1 for Raspberry Pi 4. The recipes
for this new version are coming from the master branch of layer
openembedded-core. With the newer version of Mesa Weston works
fine on Raspberry Pi 4 and the home screen appears as expected.

+Organization: O.S. Systems Software LTDA.
+
+Make sure that we are also looking for our host_os combinations like
+linux-musl etc. when assuming support for DRM/KMS.
+
+Also delete a duplicate line.
