envfs: add support of variable inode size
Introduce a struct envfs_inode_end with more data.
Today this will just containt the file mode to be able to add the symlink
support.
But this is compatible with the previous envfs version as they will do not
care about the extra as the previous version is just reading the filename and
then consume the extra data without using them.
Increase the envfs version to 1.0
