[PATCH] CODING_STYLE.rst: Be less strict about 80 character limit

[Peter Maydell <peter.maydell@linaro.org>]

Relax the wording about line lengths a little bit; this goes with the
checkpatch changes to warn at 100 characters rather than 80.

(Compare the Linux kernel commit bdc48fa11e46f8; our coding style is
not theirs, but the rationale is good and applies to us too.)

 Lines should be 80 characters; try not to make them longer.
 
 Sometimes it is hard to do, especially when dealing with QEMU subsystems
