emu-manager needs '-dm qemu' flag for migration to work correctly with
upstream QEMU. Otherwise emu-manager doesn't send
xen-set-global-dirty-log and some guest drivers may crash upon resume
(e.g. the mouse).
Treat Qemu_upstream_uefi as upstream too and pass the flag.
Commit 0e8624a introduced '-dm qemu'
but the UEFI version of the qemu profile didn't exist yet at the time.
Later commit 971d788 introduced the
UEFI qemu profile, and the build still worked due to the wildcard,
so the missing flag went unnoticed until now.
Replace the wildcard with an explicit list of when '-dm qemu' shouldn't
be added, so the next time we introduce a new qemu profile we get a
build failure and must decide which behaviour would be correct.
