nshlib/nsh_fscmds: Display modification time in ls -l output
Fixes #17063
Add modification time display to ls -l long format output.
The timestamp is shown as 'YYYY-MM-DD HH:MM' between the permission
string and the file size, following the ISO long-iso format.
Files with st_mtime == 0 (e.g., procfs, tmpfs pseudo-entries) skip
the timestamp display to avoid showing a meaningless epoch time.
