btrfs: Add zstd support to grub btrfs

Browse source 
- Adds zstd support to the btrfs module.
- Adds a test case for btrfs zstd support.
- Changes top_srcdir to srcdir in the btrfs module's lzo include
  following comments from Daniel Kiper about the zstd include.

Tested on Ubuntu-18.04 with a btrfs /boot partition with and without zstd
compression. A test case was also added to the test suite that fails before
the patch, and passes after.
