cli_classic: Add convenient '--flash-name' cli opt

We have this in the ChromiumOS fork of flashrom which we rely
on to obtain the current flash chip in use. This ports it for
upstream consumption.

V.2: Constrain number_of_operations to one as per Nico's comment.
V.3: Move two goto's outside inner if-else block.
V.4: Add missing --help line.
V.5: Add man page entry.
v.6: Use printf() directly.
