bsdinstall: do pkgbase installations with the "script" command

"bsdinstall script" will now do a pkgbase installation by default.  The
system components to install can be specified in the COMPONENTS
variable, and have the same names as those used in the interactive
installer.  bsdinstall will still do a legacy distset installation if
DISTRIBUTIONS is defined in the installerconfig file.
