init/main.c: log init process file name

Add a log message to `run_init_process()`. This log message serves two purposes. 1. If the init process is not specified on the Linux Kernel command line, the user sees, what file was chosen. 2. The time stamps shows exactly, when the Linux kernel handed over control to the init process.
