[Buildroot] [PATCH v3 1/1] package/swupdate: new package

["Jörg Krause" <joerg.krause@embedded.rocks>]

This patch is based on an WIP version submitted by Romain Naour, commented by
Arnout Vandecappelle:
https://patchwork.ozlabs.org/patch/401270/

This package provides a default configuration with all external dependencies
enabled. This is necessary because upstream does not detect which dependencies
are available. Furthermore, upstream does not implement a savedefconfig target.

Note that swupdate provides its own customized version of mongoose and
lsqlite3.

swupdate provides a default website which can be installed to the target to
enable firmware update with a browser. This patch adds the user option to
install this website.
