rust: support `srctree`-relative links
Some of our links use relative paths in order to point to files in the
source tree, e.g.:
//! C header: [`include/linux/printk.h`](../../../../include/linux/printk.h)
/// [`struct mutex`]: ../../../../include/linux/mutex.h
These are problematic because they are hard to maintain and do not support
`O=` builds.
Instead, provide support for `srctree`-relative links, e.g.:
//! C header: [`include/linux/printk.h`](srctree/include/linux/printk.h)
/// [`struct mutex`]: srctree/include/linux/mutex.h
The links are fixed after `rustdoc` generation to be based on the absolute
path to the source tree.
Essentially, this is the automatic version of Tomonori's fix [1],
suggested by Gary [2].
