package: don't hide system-wide manual pages

When MANPATH is unset or contains an empty component, a reasonable default is
used. Previously (after 3dced96741), when MANPATH
was unset, the shell hook would only place a location containing the Lix manual
pages there, and system-wide manual pages would become unavailable in the
development shell, which is undesired. Fix the issue by including an empty
component in this case.
