Assignment 2: generate_skels.py doesn't copy all required files

[nitu-catalin1998]

The script generate_skels.py for make skels does't copy all required files for assignment 2-uart:
assignments/2-uart/checker/_test/solution.ko should be copied in skels but is not and one is not able to compile homework and check it locally.

LABS=assignments/2-uart make skels
make build

make[1]: *** No rule to make target '_test/solution.ko', needed by 'solution.ko'. Stop.

Off-topic: why assignments/2-uart/checker/_test/solution.ko source code is not public? or if it is public, where is the code?

Thank you
