rust: warn if `srctree/` links do not exist

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

`srctree/` links may point to nonexistent files, e.g. due to renames
that missed to update the files or simply because of typos.

Since they can be easily checked for validity, do so and print a warning
in the file does not exist.

This found the following cases already in-tree:

warning: srctree/ link to include/linux/blk_mq.h does not exist
warning: srctree/ link to include/linux/drm/drm_gem.h does not exist
warning: srctree/ link to include/linux/drm/drm_drv.h does not exist
warning: srctree/ link to include/linux/drm/drm_ioctl.h does not exist
warning: srctree/ link to include/linux/drm/drm_file.h does not exist
warning: srctree/ link to include/linux/drm/drm_device.h does not exist
