Linter tools (`cpplint`, `checkpatch`, `shellcheck`) should use
`linter.out` as their output file. Fix the `grade.sh` script to use
`linter.out`, instead of the old, wrong `checker.out`.

Update `README.md` with current structure of directory (e.g. use `src/`
instead of `libc/`). Detail use of `grade.sh` and `make lint`.

`grade.sh` automatically grades the assignment based on the checker
(running tests for grading correctness) and linter output (for grading
coding style).

Reference solution for implementing `stat()` and `fstat()` relies on
system call being made. Include `internal/syscall.h` in corresponding
source code files to provide the `syscall()` function.

The `tests/run_all_tests.sh` script uses the `en_US.UTF-8` locale. This
may not be available on certain systems, requiring installation. Replace
it with the use of the generally available `C` locale.

Use `apt update` in the same `RUN` command with `app install`. This
prevents package synchronzation issues during installation.

Ignore `readability/todo` rule. This gives an unpleasant warning to use
`TODO(username)` as part of TODO comment items. Just allow simple `TODO`
comment items.

Ignore `build/include_subdir` rule. This gives a rather abnoxious
warning if you simply include "test.h". It should be written as
"./test.h", but that's uncommon.

Remove spacing between TODO comments and existing code. This is for
