[PATCH 3/5] qemuDomainBlockCopyCommon: Record updated flags to block job

[Peter Krempa <pkrempa@xxxxxxxxxx>]

For a long time we've masked out VIR_DOMAIN_BLOCK_COPY_SHALLOW if
there's no backing chain for the copied disk to simplify the code.

One of the refacors of caused that we no longer update the 'flags'
variable just the local copies. This was okay until in ccd4228afff I
started storing the job flags in the block job data.

Given that we modify how we call qemu we also should modify @flags so
that the correct value is recorded in the block job data.
