[PATCH 3/8] classes/staging: capture output of sysroot postinsts into logs

[Alexander Kanavin <alex.kanavin@gmail.com>]

This particularly helps with user management postinsts as otherwise
there's no trace left of what was run, in which order, and what was the output.

Here's an example from the logs:

NOTE: Running postinst /srv/storage/alex/yocto/build-multilib/tmp/work/x86_64-pokymllib64-linux/lib64-quilt/0.67/lib64-recipe-sysroot/usr/bin/postinst-lib64-base-passwd, output:
b'/srv/storage/alex/yocto/build-multilib/tmp/work/x86_64-pokymllib64-linux/lib64-quilt/0.67/recipe-sysroot-native/usr/sbin/useradd\nRunning useradd commands...\nNOTE: lib64-ptest-runner: Performing useradd with [--root /srv/storage/alex/yocto/build-multilib/tmp/work/x86_64-pokymllib64-linux/lib64-quilt/0.67/lib64-recipe-sysroot --system --no-create-home --home / --user-group ptest]\n'
