tools/compile_and_test_for_board: fix lint

[aabadie]

Contribution description

A new version of Pylint was released today and this breaks the tools-test github action because of a small inconsistency in the compile_and_test_for_board script.

The raised issue is perfectly valid and this PR is fixing it by cleaning up a bit the make_with_outfile function. The return value of this function is never used so a bare return or no return is ok.

RIOT/dist/tools/compile_and_test_for_board/compile_and_test_for_board.py

Line 410 in e0211f4

self.make_with_outfile('compilation', compilation_cmd)

RIOT/dist/tools/compile_and_test_for_board/compile_and_test_for_board.py

Lines 418 to 419 in e0211f4

	self.make_with_outfile('test', self.TEST_TARGETS,
	save_output=True, setuptasks=setuptasks)

Testing procedure

compile_and_test_for_board.py works as expected:
