  1. Add AIX support with fcntl 

    AIX doesn't provide a true flock() syscall. It does exist but it's just
a wrapper around fcntl. It doesn't provide safe locks under file
descriptors of a same process.

The current implementation is based on the file
cmd/go/internal/lockedfile/internal/filelock/filelock_fcntl.go.

Using fcntl implementation doesn't allow to have several RLocks at the
same time as closing a file descriptor might release the lock if even
others RLocks remain attached.
