fadump: use 'zstd' as the default compression method

Browse Source 
If available, use 'zstd' compression method to optimize the size of
the initrd built with fadump support. Also, 'squash+zstd' is not
preferred because more disk space is consumed with 'squash+zstd' due
to the additional binaries needed for fadump with squash case.
