>Description:
Currently the backup script archives a full path starting from '/' and then strips the leading slash off of the path which is correct. Upon extraction that full path without the leading slash is extracted in the current directory as var/db/pkg/<contents> with the first two and possibly more directories left empty.

If a user has a different PKG_DBDIR as designated by ports(7) that is larger this can lead to frustration with the length of emptiness in the archive with the leading paths.
	
>How-To-Repeat:
Run ( /etc/periodic/daily/220.backup-pkgdb ) and extract the archive located in /var/backups/
	
>Fix:
This patch makes 220.backup-pkgdb respectifully cd to where the pkgdb is located and create the archive from the relative path so there is only the pkgdb directory and contents upon extraction.
