Change the use of asm/atomic.h to require -DGIT_HAS_ASM_ATOMIC

These headers aren't always available; they typically come from the
Linux kernel, but aren't supposed to be exported into the userspace
/usr/include.  Modern kernels won't install these and some distros
rm -rf the directory post kernel header install.
