machines/sternenseemann/wolfgang: fix alternate scroll for git diff

Even if GIT_PAGER is set to less alone, git diff will pass extra options
to less, so we have to explicictly set the LESS="..." environment
variable to change this behavior. Specifically we don't want -F which
prevents less from entering alternate mode which enables alternate
scrolling in foot.
