pkgadmin: Workaround missing /usr/local/bin path in cronjob

Currently pmirror resides in /usr/local/bin (which is not optimal) and
/usr/local/bin is not incluided in the default path. As a
non-interactive bash or one that is called as /bin/sh (as cron does)
does not read .bashrc, we don't have /usr/local/bin in the path.
However, the pkgadmin command expected "pmirror" to be in the path.

As a workaround, until the default path is updated to include
/usr/local/bin (and /usr/sbin ?) , read our .bashrc to get all
PATHs we are used to.

Another workaround would be to set SHELL an BASH_ENV in the crontab file
to have all of the .bashrc settings.

    SHELL=/usr/bin/bash
    BASH_ENV=./.bashrc
