chore: improve 'test' command on builder
chore: improve 'test' command on builder

test doesn't increase build info. so it makes the c++ compiler compiles
units which has been changed by new commit.
'dbg', 'rel' command will compiles whole source codes if there is tiny
updation among those codes.

and now 'test' command can take the tc filename to be executed.
e.g.
    python3 builder.py test wrdTest
