[PATCH] response: convert source arg to path before IO.copy_stream

[PATCH v2] response: convert source arg to path before IO.copy_stream

[Eric Wong]

This will allow us use the sendfile syscall under Linux on
Ruby which favor #read/#readpartial methods for non-IO objects.

This also allows us to revert changes made in
commit db790ff3531acdfa23ab290998bba29360a6782b
("sync_close: This fix breakage from Ruby-trunk r50118")
