[simplified patch, bumped PKG_RELEASE, cleaned message]
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.

Busybox built against musl-libc will choke on these otherwise, besides that
it is more natural to use the filesystem type, then options, then name, then
mountpoint.
