Function btrfs_scan_devices() is being used by commands such as
'btrfs filesystem' and 'btrfs device', by having the verbose argument in
the btrfs_scan_devices() we can control which threads to show the
verbose when verbose is enabled by the global verbose option.

So add an option %verbose to btrfs_scan_devices().

v1.1: drop stale #include <stdbool.h> as %bconf.verbose is now int
