kbuild: Fix size_append issue for bzip2/lzma kernel

The Makefile.lib will call "echo -ne" to append uncompressed kernel size to bzip2/lzma kernel image. The "echo" here depends on the shell that /bin/sh pointing to. On Ubuntu system, the /bin/sh is pointing to dash, which does not support "echo -e" at all. Use /bin/echo instead of shell echo should always be safe.
