net: fix sendfile regression with io.Copy on macOS

Since CL 472475, io.Copy can no longer use sendfile on macOS for copying
files to a socket due to a too strict type assertion. This CL fixes the
issue by checking for the necessary interfaces instead of the concrete
os.File type in sendfile_unix_alt.go.

Fixes #66988
