[git commit] httpd: fix sendfile of files larger than 2 Gb. Closes 4754

[Denys Vlasenko]

commit: http://git.busybox.net/busybox/commit/?id=ef43beac63aa7e4b2bccb069e47b5e4902bb895f
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

When built with "sendfile" support, httpd was unable to send large files
(>2 GB) in one single connection, terminating it before the full file
has been sent.
