[PATCH 5/5] nodewatcher: Use Makefile version for nodewatcher data

[Adrian Schmutzler]

So far, nodewatcher version has to be specified twice, once in the
Makefile and again in the nodewatcher script.

With this patch, a version file is created during build than can
be read in nodewatcher script, so version only has to be specified
once anymore. The file name mimics the version files already present
for OpenWrt and our firmware.
