util/gitconfig: Support dash in pre-commit hook
On debian systems, /bin/sh is `dash` which has built-in `echo` always
interpreting escape sequences such as '\n'. The pre-commit hook uses
the built-in for piping diff to checkpatch, interpreting the diff's
escape sequences in the process and leading to false negatives
and preventing commits despite conformance.
Use `printf` instead of `echo` when handling diff content. The bug was
introduced in commit ef869305 (util/gitconfig: update pre-commit
script).
