kheaders: remove unneeded 'cat' command piped to 'head' / 'tail' commit 9a066357184485784f782719093ff804d05b85db upstream. The 'head' and 'tail' commands can take a file path directly. So, you do not need to run 'cat'. cat kernel/kheaders.md5 | head -1 ... is equivalent to: head -1 kernel/kheaders.md5 and the latter saves forking one process. While I was here, I replaced 'head -1' with 'head -n 1'. I also replaced '==' with '=' since we do not have a good reason to use the bashism.
