added two new options pkgaddopts and wgetopts

so we are able to specify options for pkgadd and wget used by pkgutil.
added options, support an array of mirrors

use $pkgaddopts and $wgetopts from init.pp to specify options pkgutil
should use when calling pkgadd and wget.

support multiple mirrors in pkgutil.conf.
