[PATCH 2/3] Fix memleaks in cli_classic.c.

[Stefan Tauner]

Frees the memory allocated for the following strings
- log file name
- layout file name
- image file name
- programmer parameter (and reset the associated global variable in flashrom.c)

Also, free the flashchip structs allocated by probe_flash.

The layout image names were not fixed due to the pending layout patches.

These bugs were found thanks to valgrind.
