write_object_file_literally(): use size_t

Browse Source 
The previous commit adds a test that demonstrates a problem in the
`hash-object --literally` command, manifesting in an unnecessary file
size limit on systems using the LLP64 data model (which includes
Windows).

Walking the affected code path is `cmd_hash_object()` >> `hash_fd()` >>
`hash_literally()` >> `hash_object_file_literally()`.

The function `hash_object_file_literally()` is the first with a file
length parameter (via a mem buffer). This commit changes the type of
that parameter to the LLP64 compatible `size_t` type.

There are no other uses of the function. The `strbuf` type is already
`size_t` compatible.

Note: The hash-object test does not yet pass. Subsequent commits will
continue to walk the call tree's lower level functions to identify
further fixes.
