  REGRESSION(263809 at main): [UNIX] SharedMemory::map is leaking the file descriptor
https://bugs.webkit.org/show_bug.cgi?id=258275

Reviewed by Michael Catanzaro.

Once mapped, we don't need to keep the file descriptor open. Before
263809 at main, we cleared the file descriptor after the mmap call, then
created an instance with -1 as fd. Now we are creating the new instance
with the handle fd moved.
