net: avoid darwin/arm64 platform bug in TestCloseWrite
On darwin_arm64, reading from a socket at the same time as the other
end is closing it will occasionally hang for 60 seconds before
returning ECONNRESET. (This is a macOS issue, not a Go issue.)
Work around this condition by adding a brief sleep before the read.
Fixes #49352 (we hope).
Updates #37795.
