[0/2] Remove locking.sh dependency on perl

Message

Perl is a large dependency for locking.sh's single use of comparing a
file descriptor's and a file's inodes.  Many systems don't otherwise
require perl, so dropping this use eliminates the dependency.

Replace the open-coded perl with an equivalent C implementation.

  tools/helpers: Introduce cmp-fd-file-inode utility
  Linux/locking.sh: Use cmp-fd-file-inode for lock check
