AU: Many minor cleanup changes

postinstall: Run postinst twice, once for pre-commit (ie, before we
mark the install partition bootable in the partition table), and
post-commit (for after we do). This behavior is needed for specific
types of firmware update.

download action: flush caches, as we found was necessary in
memento_updater.sh

omaha request prep action: update the names of keys we look for in
lsb-release, also get the AU server url from a file, rather than
hard-code it.

set bootable flag action: GPT support.

also, some misc utility functions.

BUG=None
