[PATCH 06/38] perf tools: Remove condition in machine__get_kernel_start_addr.

[Arnaldo Carvalho de Melo <acme@infradead.org>]

From: Dongsheng Yang <yangds.fnst@cn.fujitsu.com>

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.
