[Qemu-trivial] [PULL 19/22] gdbstub: Use qemu_set_cloexec()

[Michael Tokarev]

From: Peter Maydell <address@hidden>

Use the utility routine qemu_set_cloexec() rather than
manually calling fcntl(). This lets us drop the #ifndef _WIN32
guards and also means Coverity doesn't complain that we're
ignoring the fcntl error return (CID 1005665, CID 1005667).
