[yocto] How to patch sysroots file?

generate the patch file for the sysroots

Will, there is task called do_populate_systroot which will generate
sysroots files/headers.

If you want to generate the patch, you don't require to generate "sysroot
patch" but you need to know from which package the sysroot files are
generated. And in your case it might be "libc-headers" so you need to
create patch for "libc-headers" recipe. So at the end, it will
automatically reflect in the sysroot path.
