libflashrom/fmap: Don't use off_t for flash offsets

off_t is a special POSIX type that is used to represent file offsets in
certain APIs (e.g. lseek(), mmap()), and should not be reused to
represent anything else (such as flash offsets). In particular, the
width of the type may change based on the definition of the
_FILE_OFFSET_BITS macro. Using such a type at the libflashrom interface
is particularly dangerous, because if a program is built with a
different _FILE_OFFSET_BITS value than libflashrom, the resulting ABI
corruption will cause very very nasty and confusing bugs. This patch
replaces all instances of off_t that are not related to file offsets
with (s)size_t.
