Recreate gcc8-fix-put-user.patch without context

gcc-fix-put-user.patch doesn't apply cleanly to any kernel that includes this commit or a backport of it because the surrounding lines (context) of the patch are different.

This MR fixes the problem by removing the context from the patch. It also changes linux-sony-amami, linux-sony-aries, and linux-sony-taoshan to use the shared patch.

I have confirmed that all six affected kernels still compile.
