test: log functions with CONFIG_LOG=n 

If CONFIG_LOG=n, we still expect output for log_err(), log_warning(),
log_notice(), log_info() and in case of DEBUG=1 also for log_debug().

Provide unit tests verifying this.

The tests depend on:

	CONFIG_CONSOLE_RECORD=y
	CONFIG_LOG=n
	CONFIG_UT_LOG=y

It may be necessary to increase the value of CONFIG_SYS_MALLOC_F_LEN to
accommodate CONFIG_CONSOLE_RECORD=y.
