launch: Handle guestfs_config qemu_value == NULL.
The second parameter to 'config' may be NULL.
In commit 52fa23d74f6308daf804c2330b0b27e0b4412594 (refactoring of
guestfs_config) the code this got lost, and guestfs_config would
segfault if qemu_value was NULL.
Also this fixes the libvirt method to handle the same case.
I checked libguestfs-1.18 and -1.16 branches, and this problem does
NOT affect them.
