package/systemd: fix build on not-recent distros

Browse Source 
systemd is at it again, using ln --relative once more, which is not
available but on the most recent distros.

Patch it out with a bit of sed magic.

Subject: [PATCH] install: don't use ln --relative
ln --relative is too recent to be available in most distros, so it
breaks the build.
Fix that with a bit of sed magic, that turns constituents of the
destination directory each into ../ , which when appended to the
destination directory leads back straight to / .

The problem is even more visible when doing cross-compilation in
professional build farms, which are often stuck to years-to-decade-old
enterprise-grade distributions (because, IT), even if the target system
is top-notch up-to-date.
