marsadm: fix /mars security issues
...
Only relevant for non-storage servers where customers have access to.
Notice that /mars is a _reserved_ filesystem for MARS-internal purposes.
It has mothing to do with an ordinary filesystem.
Users have generally to be kept out.

infra: fix potential fault
...
Very old idiotic bug.
Under some circumstances, a byte beyond the end of a non-null-terminated
string (such as produced by the VFS) might be read, potentially leading
to a page fault just one byte after a page border.

Don't allocate this on the stack, it might grow too big in future.
