perf kvm: Fix spurious '=' use in man page
...
As option --host and --guest request no input for it, there should not
be a '=' after them in the man page sources.
And --output expects a filename as the input, so there should be a '='
after it.
This patch removes the needless '=' after --guest and --host, and adds a
'=' after --output in perf-kvm.txt.

perf kvm: Add more detail about buildid-list in man page

As the buildid is read from /sys/kernel/notes, then if we use perf kvm
buildid-list with a perf data file captured by perf kvm record with
--guestkallsyms and --guestmodules, there is no result in output.
This patch add a explanation about it and add a limit of using perf kvm
buildid-list.

perf target: Move the checking of which map function to call into function.

Check for cpu_map__dummy_new() or cpu_map__new() to be called in
perf_evlist__create_maps() is more complicated.
This patch moves the checking work into target.h, combining two
conditions and making perf_evlist__create_maps() more readable.

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.
