Fix build with kernel < 5.9
linux/close_range.h is only available since kernel 5.9 and
https://github.com/torvalds/linux/commit/60997c3d45d9a67daf01c56d805ae4fec37e0bd8
resulting in the following build failure:
../util/fusermount.c:40:10: fatal error: linux/close_range.h: No such file or directory
So let's check for header presence and emit HAVE_LINUX_CLOSE_RANGE_H
accordingly and check for it when including <linux/close_range.h> and
calling close_range() instead of checking for close_range() function in
meson and check against HAVE_CLOSE_RANGE.
