package: don't hide system-wide manual pages
When MANPATH is unset or contains an empty component, a reasonable default is used. Previously (after3dced96741
), 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. Change-Id:Ib3c67a831d709fe2a87520e15917eebb59397bd1
