Rename _require_btrfs() to _require_btrfs_subcommand() to avoid
confusion, as all other _require_btrfs_* has a quite clear suffix, like
_require_btrfs_mkfs_feature() or _require_btrfs_fs_feature().
Also enhance _require_btrfs_subcommand() to accept 2nd level commands or
options.
Options will be determined by the first "-" char.
This is quite useful for case like "btrfs inspect-internal dump-tree"
and "btrfs check --qgroup-report".
