7a5002ec9d base-files: add /etc/shadow to list of essential files to keep in sysupgrade (bug 18206)
Based on bug  sysupgrade can lead to loss of password information in
certain situations. Most likely all users who will upgrade from versions
r43017-43040, will lose their current passwords. :-(
https://dev.openwrt.org/ticket/18206

Currently /etc/shadow is defined as a conffile in base-files:
https://dev.openwrt.org/browser/trunk/package/base-files/Makefile#L37

But it is not defined in the default list of essential files to keep in
sysupgrade:
https://dev.openwrt.org/browser/trunk/package/base-files/files/lib/upgrade/keep.d/base-files-essential

If exporting conffiles info fails, /etc/shadow can get lost.

Shadow passwords are now the default, so saying that preserving /etc/passwd
is essential while /etc/shadow is not, makes no sense.

The attached patch adds /etc/shadow to the list of essential files.
