Vincent Franchomme 3cfd8ab775 [BTRFS][UBTRFS][SHELLBTRFS] Upgrade to 1.7.8 (#4417) 
v1.7.8.1 (2021-06-13):

- Fixed bug preventing new directories from appearing in listings
- Fixed Release version of driver still not working on XP

v1.7.8 (2021-06-09):

- ~~Upgraded zstd to version 1.5.0~~ Not in ReactOS as it introduces deprecated code
- Fixed regression stopping driver from working under XP
- Fixed compilation on clang
- Fixed corruption issue when Linux mount option inode_cache had been used
- Fixed recursion issue involving virtual directory \$Root
