Move the main() function from flashrom.c to cli_classic.c

The file flashrom.c is part of libflashrom and should thus not contain a
main() function, that would break compilation of all frontends using
libflashrom. Also, cli_classic.c is the right place anyway, as it's the
main() of the CLI tool.

Rename the simple wrapper cli_classic() in cli_classic.c to main(), as
it's not really needed.

Corresponding to flashrom svn r1417.
