When installing or deinstalling a package, it is not enough to lock the

WRKDIR against foreign processes. Instead, the PKG_DBDIR is locked,
preventing other (pkgsrc) processes from modifying the set of installed
packages while another one is doing that.

This allows to use "bmake update" efficiently on multi-processor
machines by just running it in four different package directories.

Note that the pkg_add and pkg_delete tools may still interfere with this
locking when they are directly run.
