In the autotools build, it only built in-tree, from cwd = doc/ and
resolving doc/../lib/libalpm
In the meson build, this accidentally worked if cwd =
pacman/builddir/ and resolved to builddir/../lib/libalpm/
But... this should always have been configured with the actual path to
the inputs. So, we will now proceed to do so.
Fixes building man3 if your out of tree builddir doesn't happen to be a
direct subdirectory of the source root.
