[Buildroot] [git commit branch/next] package/swupdate: specify SWU_VER during build

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=0b4a9930124f7fb4c7bfae281db900905006a2da
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

The swupdate build process uses SWU_VER as part of the build commandline
for compiling objects to define the value for use in globals.h (see also
Makefile.flags).

This value is also used to communicate capabilities to lua handlers
(see upstream 0f38ff186e76c55c8d00ccb53739a29bcca91445).

When swupdate gets built, SWU_VER defaults to using `git describe` to
determine the version. This, unfortunately, picks up the version of the
Buildroot checkout and not the actual version of swupdate.

Now, specify SWU_VER as part of the make options to override the
calculated value so the proper version is reported.
