Change hardcoded ../common paths, which will break when moving the
project specific manuals in other repositories, to ./common so they
use the dynamically created symlink that always points to the right
path.
(moving manuals to project repositories 9/19)

The manuals existed in different form for several years in an internal
sysmocom repository. However, since they had just recently been
converted from docboox-xml to asciidoc and all files have been
re-shuffled for enabling the public release, there's not much point in
keeping the history with git-filter-branch.
