Common config.fs/$TARGET_FS_CONFIG_GEN AID/fs configuration
file for all chipset inheriting from base.mk.
Since legacy device-specific android_filesystem_config.h and
config.fs do not co-exist, temporarily include config.fs only
if legacy file is absent. Once all legacy, device-specific
files have been deleted, config.fs can be made unconditional.
