gcc-descr: by default show revision for HEAD

I've made the mistake multiple times while doing a bisection.
One would expect that gcc-descr w/o an argument would print
revision for the current HEAD and not master.
Thus change it.

contrib/ChangeLog:

	* git-descr.sh: By default print revision for HEAD.
