ci/bare-metal: build full piglit for baremetal ARM targets.

ci/bare-metal: build full piglit for baremetal ARM targets.

ARM64 had it for traces only, upgrade it to a full build so we can test
a630.  We also add it for armhf, as we'll want it on both rpi and etnaviv.

Bumped the LAVA tag as well, since the script changes a bit and it does
impact the final image (even if we aren't pulling in full piglit there
yet).  Note I also had to drop the "v" on the tarring of their rootfs, as
the verbosity on baremetal was exceeding job log size.
