kernel: btrfs: enable ACL

By default CONFIG_BTRFS_FS_POSIX_ACL is disabled, it should be enabled
only when you enable CONFIG_FS_POSIX_ACL.

Right now, when you enable CONFIG_FS_POSIX_ACL it will enable
CONFIG_BTRFS_FS_POSIX_ACL, but it will be disabled once you install
kmod-btrfs. This should prevent it.

Btrfs has enabled by default ACL for mount option.
