Subject: [PATCH 01/12] tools/nolibc: use 64-bit ino_t

The kernel uses 64-bit values for inode numbers.
Currently these might be truncated to 32-bit when assigned to
nolibc's ino_t values.

Switch to 64-bit ino_t consistently.

As ino_t is never used directly in kernel ABIs, no systemcall wrappers
need to be adapted.
