When trying to build shadow in a different directory I stumbled upon few
issues, this commit aims to fix all of them:
- The `subid.h` file is generated and hence in the build directory and
not in the source directory, so use `$(builddir)` instead of
`$(srcdir)`.
- Using `$<` instead of filenames utilises autotools to locate the files
in either the source or build directory automatically.
- `xsltproc` needs to access the files in login.defs.d in either the
source directory or the symlink in a language subdirectory, but it
does not interpret the `--path` as prefix of the entity path, but
rather a path under which to locate the basename of the entity
from the XML file. So specify the whole path to login.defs.d.
- The above point could be used to make the symlinks of login.defs.d
and entity path specifications in the XMLs obsolete, but I trying
not to propose possibly disrupting patches, so for the sake of
simplicity just specify `$(srcdir)` when creating the symlink.

The content of the man pages however is dependent on compile flags. So the
pre-built ones might not fit your version of shadow. To build them yourself use
--enable-man. Furthermore the following build requirements will be needed:
