Makefile: suppress error messages from 'git'.

If you have a clone of the 'wiggle' git tree but with no
tags, then "git describe HEAD" will complain
   fatal: No names found, cannot describe anything.
As it produces no output, the compiled in default will be used
so this is just an unnecessary message.  So send it to /dev/null.
