toolchain-shar-template.sh: fix the text files in the top dir
It only fixed the text files in native_sysroot, but there might be some
files in the top installed dir (whose var name is target_sdk_dir in the
code) which are also needed to be fixed.
It used "find $native_sysroot", now also "find $target_sdk_dir -maxdepth 1",
and split the long line into small ones.
