builtin-run: Fix console= parameter concatenation

Commit 5857730ceee5 ("builtin-run: Pass console= parameter based on
active console") adds a console parameter to the kernel command line,
but doesn't account for x86 kvm__arch_set_cmdline populating
real_cmdline without adding a space. Fix the concatenation.
