Bug#696295: webkit: Sets FD_CLOEXEC incorrectly with F_SETFL instead of F_SETFD

This package contains code that tries to set the FD_CLOEXEC flag for a
file descriptor, but it does using F_SETFL instead of F_SETFD.
Using that value on F_SETFL is just wrong, and might make the call fail
on some systems, as it's requesting to set an undetermined flag. For
example on GNU/* FD_CLOEXEC has value 1, which matches with O_WRONLY.
This might cause the code to at least leak file descriptors, and at
worst to terminate execution.
Attached a patch fixing this.
