[PATCH 5/5] dim: store Link: in MERGE_MSG in apply-pull

[Daniel Vetter]

This way there's no need for a dim apply-pull-continue, plain old git
commit is enough.

Aside: We might want to do the same trick for dim apply-branch, but
git am is a bit harder to script.

v2: Drop cat, use shell redirects to appeas shellcheck.
