ext2fs: dynamically allocate ext2_lifeboat payloads via mmap
Previously, the ext2_lifeboat payloads array was statically sized
with a hardcoded 4096-byte assumption, which breaks on filesystems
formatted with different block sizes.
Changing the payload to a pointer and allocating it dynamically via
mmap() during journal creation solves two issues:
1. It scales correctly with the actual block_size of the filesystem.
2. The virtual memory manager inherently provides page-aligned memory,
which should help with performance.
