qemu: avoid adding "" in smbios arguments 

The log lists things like -smbios type=1,vendor="Red Hat", which
is great for shell parsing, but not so great when you realize that
execve() then passes those literal "" on as part of the command
line argument, such that qemu sets SMBIOS with extra literal quotes.

The eventual addition of virCommand is needed before we have the API
to shell-quote a string representation of a command line, so that the
log can still be pasted into a shell, but without inserting extra
bytes into the execve() arguments.

* src/qemu/qemu_conf.c (qemuBuildSmbiosBiosStr)
(qemuBuildSmbiosSystemStr): Qemu doesn't like quotes around uuid
arguments, and the remaining quotes are passed literally to
smbios, making <smbios mode='host'/> inaccurate.  Removing the
quotes makes the log harder to parse, but that can be fixed later
with virCommand improvements.
* tests/qemuxml2argvdata/qemuxml2argv-smbios.args: 'Fix' test; it
will need fixing again once virCommand learns how to shell-quote a
potential command line.
