[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.
