Adept layout handling to new programmer infrastructure and fix off-by-one error

Browse Source 
Flashrom has the ability to use layout files with romentries, but
this feature was not adapted to the programmer infrastructure and had
undefined behaviour for flasher!=internal. The romentry handling had an
off-by-one error which caused all copies to end up one byte short. Fix
these issues.

Corresponding to flashrom svn r694.
