[Qemu-devel] build failure with coroutine-gthread

["Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com>]

  LINK  qemu-ga
coroutine-gthread.o: In function `coroutine_init':
/home/opensource/sources/qemu/qemu-upstream/coroutine-gthread.c:39: undefined reference to `g_thread_init'
collect2: ld returned 1 exit status

The below patch fix the failure.  I also added the patch in the VirtFS
pull request.

    coroutine: add gthread dependency
    
    Commit 1fc7bd4a86a2bfeafcec29445871eb97469a2699 removed the gthread and
    gio dependency since qemu-ga did not require it.  Coroutines require
    gthread, so add it back in.
