KVM: selftests: Refactor help message for -s backing_src
All selftests that support the backing_src option were printing their own description of the flag and then calling backing_src_help() to dump the list of available backing sources. Consolidate the flag printing in backing_src_help() to align indentation, reduce duplicated strings, and improve consistency across tests. Note: Passing "-s" to backing_src_help is unnecessary since every test uses the same flag. However I decided to keep it for code readability at the call sites. While here this opportunistically fixes the incorrectly interleaved printing -x help message and list of backing source types in dirty_log_perf_test.
