Triggered by commit 309b81f0fdc4 ("selftests/bpf: Install generated test progs") It requires to change the rule which rely on the one shell behaviour (run_tests). Simplify also INSTALL_SINGLE_RULE, remove extra echo, required to workaround .ONESHELL.

In case of blank $(TEST_PROGS) it will be expanded to blank, so no need for extra check; 2) $(OUTPUT) is always initialized to current dir or supplied value, so it does not make any harm to add it unconditionally.
