sha1_file: don't convert off_t to size_t too early to avoid potential die()sp/stream-clean-filter

xsize_t() checks if an off_t argument can be safely converted to
a size_t return value.  If the check is executed too early, it could
fail for large files on 32-bit architectures even if the size_t code
path is not taken.  Other paths might be able to handle the large file.
Specifically, index_stream_convert_blob() is able to handle a large file
if a filter is configured that returns a small result.
