dracut has apparently moved from /sbin to /bin some time in the past.
Accommodate this change to avoid failures.

By default dracut set 600 mode. While it isn't a problem for starting a
VM (which is done as root), it is a problem for creating standalone VM,
which has it's own copy of kernel directory.
The module is required by gui-agent, so make sure it will be actually
installed. This would also install the module in dom0 (when
qubes-kernel-vm-support is installed there), but this this is harmless.
QubesOS/qubes-issues#1354
At the moment, Xen has a 16TB limit on x86, so this has no practical
impact, aside for silencing compiler truncation warnings.
Also, the rest of the GUI/u2mfn code and protocol would need to be
expanded to use 64-bit mfns for Qubes to actually work there.
This is preparation for pvgrub support, where all VM kernel files will
be installed inside of VM instead of dom0.
But also the same could be used to prepare VM kernel image from any dom0
kernel.
