dpkg: save output of postinstall scripts when image firstboot

When image feature "debug-tweaks" enabled, save output of postinstall
scripts to log file /var/log/postinstall.log when image first boot. And
the log file can be configured.

It also needs image feature "package-management" enabled. If not,
package run-postinsts will be installed and then all packages will be
configured by it. Command 'dpkg --configure' outputs nothing.
