Let --enable-lock-counter build an additional emulator
"./configure --enable-lock-counter" would modify the behavior of the default emulator (usually SMP). To make lock counting more accessible, change --enable-lock-counter to build an additional emulator in the same way as: (cd erts/emulator && make lcnt) (The next commit will make it easier to start the built lock-counter emulator.)
