High level helper function to serialize an entire file system tree to
a squashfs inode table and directory table.
The data is written to the given file descriptor and the super block is
update accordingly (inode and directory table start and total size).
The function internally creates two meta data writers and uses
meta_writer_write_inode to serialize the inode table of the fstree.
Returns 0 on success. Prints error messages to stderr on failure.
