flashrom: ensure flashrom symbols are not loaded if !USE_FLASHROM

The linking process during the installation phase of this package
breaks if you compile with make USE_FLASHROM=0. A new conditional has
been added to the make file that prevents utility/crossystem from
compiling if USE_FLASHROM is either not set or set to the number 0.
