[PATCH] kbuild: fix out-of-tree build missing gpio.h

[Casey Connolly]

When building out-of-tree $(srctree) is typically a relative path, the
kbuild 6.1 sync uses it in more places where KBUILD_SRC was used leading
to issues like this where we create broken symlinks.

Fix this by creating the symlink with an absolute path like the old
behaviour.
