btrfs: sysfs: remove BIG_METADATA feature files

Browse Source 
This flag has been merged in 3.10 and is effectively always-on. Its
status depends on the host page size so there's another way to guarantee
compatibility with old kernels.

Due to a bug introduced in 6f93e834fa ("btrfs: fix upper limit for
max_inline for page size 64K") the flag is not persisted among features
in the superblock so it's not reliable.
