perf tools: Remove condition in machine__get_kernel_start_addr.
In machine__get_kernel_start_addr, the code, which is using machine->root_dir to build filename, works for both host and guests initialized from guestmount, as root_dir is set to "" for the host machine in the machine__init() function. So this patch remove the branch for machine__is_host.
