[PATCH v1] perf doc: Improve perf trace's doc on --force-btf option

[Howard Chu]

As mentioned by Arnaldo in a past discussion (Link:
https://lore.kernel.org/linux-perf-users/Z2m0pWiQgZNXhvxK@x1/), the
current documentation on --force-btf is vague and inaccurate, this patch
aims to provide a clearer explanation of the option.
