[Refactor:Developer] Replace submitty_count (#56)

### What is the current behavior?
Fixes Submitty
[Issue#11784](Submitty/Submitty#11784) - This
one of the companion PRs to Submitty
[PR#12609](Submitty/Submitty#12609).
The tutorial courses 04 - Python Static Analysis, 06 - Loop Types, and
07 - Loop Depth all use `submitty_count` in their autograding configs.
This command is being deprecated, so we should update it.

### What is the new behavior?
`submitty_count` has been removed from `04 - Python Static Analysis` and
`06 - Loop Types` and replaced with `submitty_count_ts` in preparation
for deprecation. For `07 - Loop Depth`, there was no equivalent
functionality present in `submitty_count_ts` so the testcase is entirely
commented out.

### Other information?
<!-- Is this a breaking change? -->
This specific PR is not a breaking change. However, the other PRs
accompanying this one are breaking PRs.
<!-- How did you test -->
Tested that all homework configs still build and their accompanying
still submissions work as intended.

[Bugfix:Autograding] add dwarf 4 option to drmemory (#39)

with g++11 it is necessary to compile with dwarf4 to get line numbers
from DrMemory

            "command" : "clang++ -g -gdwarf-4 -Wall -o a.out *.cpp",
// NOTE: Compiling with the -gdwarf-4 option is required with g++ 11+
            // so that DrMemory can print source code line numbers with.
            // See also:
            // DynamoRIO/drmemory#2485

Also, in PR Submitty/Submitty#9793 the category
for a system call previously in the unknown category is updated so that
the configuration runs without the system call failure.
