On systemd, it set RLIMIT_NOFILE to 512k, since do_testimage
for core-image-sato-sdk has memory limitation (256Mib) which
caused rpc.statd failed with out of memory.
[ 531.306146] Out of memory: Kill process 193 (rpc.statd) score 200 or sacrifice child
The rpc.statd and rpc.mountd allocates memory according to
RLIMIT_NOFILE, so decrease it to 4k to keep sync with sysvinit
After applying the patch, the memory cost is the same with sysvinit:

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
