Enable usrmerge

An increasing number of advanced systemd features with respect to immutable systems and sandboxing are effectively dependent on the usrmerge distro feature, so it seems reasonable to enable it since upstream AGL currently requires systemd usage. See SPEC-4352 for more detailed discussion of rationale. Changes: - Add usrmerge to AGL_DEFAULT_DISTRO_FEATURES in poky-agl.conf. - Add workarounds via bbappends in meta-agl-bsp for the assumption of using /lib instead of ${nonarch_base_libdir} in various meta-rcar-gen3 kernel module recipes. This will be followed up with upstream to hopefully fix the recipes. - Replaced some explicit /sbin usage with ${sbindir} in the initramfs-netboot recipe used by the agl-netboot feature to avoid packaging errors.
