Legacy GSI had been changed to include BoardConfigGsiCommon.mk instead of treble_common*.mk. However, some default settings are different than the original. This patch fixes BOARD_BUILD_SYSTEM_ROOT_IMAGE in Legacy GSI makefiles. The patch also removes redundant settings and fix some comments. Bug: 122282239 Test: make Change-Id: Ie4eb8cf410bfd2edc74648c0e5ee81028242a1b7
