Kernel cmdline args can be passed to xen pv domains even when a

ignores cmdline when bootloader is present.
Since the xend sub-driver is used with many xen toolstack versions,
this patch takes conservative approach of adding an else block to
existing !def->os.bootloader, and only appends sxpr if def->os.cmdline
is non-NULL.

ACK, assuming the test cases still pass - I'm surprised this
doesn't require any testcase fixes
It should require a new testcases too. :)
