Refine revision handling

Up to now, when compiling flashrom outside a VCS it would print two
warnings that are not very clear to the user. This patch adds a new
auxilary function to getrevision.sh and uses it in the makefile to print a
single and more meaningful message to the user while hiding the
warnings from getrevision.sh.

Corresponding to flashrom svn r1862.
