Abhishek Mishra 72192fc8bc fs/binfmt: Enforce POSIX execute permissions prior to binary load 
Adds a pre-load permission check in exec_internal() to verify the
calling task has the required execute (x) bits for the target file.
Properly evaluates root (euid == 0), owner, group, and other permissions.

This ensures POSIX compliance and cleanly rejects unauthorized files
with -EACCES before they reach the ELF loader, preventing unnecessary
memory allocation and downstream hardware execution faults.
