Sergey Ryazanov 880c1f0336 base-files: prevent issues w/ overlay on powerloss after sysupgrade
Due to filesystem write caching the old configuration data could stay
out of flash for a long time during a first boot after the sysupgrade.
Power loss during this period could damage the overlay data and even
make device inaccessable via the network.

Fix this by syncing data to a flash as soon as the previous
configuration will be unpacked after the sysupgrade. Also sync the FS
state after the sysupgrade.tgz archive removing to prevent duplicative
extraction of a previous configuration.

Tested with AMD Geode based board.

02_default_set_state base-files: preinit: Fixed sourcing of diag.sh in /etc/preinit. This caused errors due to frequent use of /proc/cpuinfo to determine board name to pick led layout. Now diag.sh (which only defines set_state and any helper functions) is sourced by a proper preinit function during preinit_main, which is after /proc has been brought up, unlike in /etc/preinit 13 years ago
