build system: add setlocalversion

Version is built from git commit id, for example wmfs-ga33ec04-dirty
-> 'g', this is a git repo
-> a33ec04 is the beginning of the commit id (sha1)
-> dirty mean that there is uncommitted changes

wmfs users gives their 'wmfs -v' and developers can easily identify wmfs
version.

Move status.sh to scripts/ with setlocalversion
