LU-15002 utils: disable meta_bg and enable packed_meta_blocks

To take advantage of the upcoming e2fsprogs changes,
disable meta_bg to allow group descriptor blocks allocate
beyond group#0. This allows the group descriptor blocks
to be packed and placed at the beginning, rather than
distributed across the entire file system with meta_bg.

Enable packed_meta_blocks to place bitmaps, inode table
and journal at the beginning of the file system.

Due to LU-16971, use 200 blocks when testing mke2fs options.

Re-enable lazy_journal_init, which got turned off accidentally.

Fix up the handling of extented options, there should be spaces
in front and after -E when building the mke2fs cmd.
