clang-format: Set IndentWrappedFunctionNames false

The true option causes this indenting for functions:

static struct something_very_very_long *
    function(void *arg)
{

While a quick survey suggests that the usual Linux fallback is the GNU
style:

static struct something_very_very_long *
function(void *arg)
{

Eg as seen in:

kernel/cpu.c
kernel/fork.c
etc
