The helper function is_mapping_symbol() historically checks for both
local labels prefixed with ".L" or "L0" and mapping symbols prefixed
with "$".

Rename it to is_ignored_kernel_symbol() to better reflect this actual
behavior and scope, preventing conceptual confusion.

I think is_ignored_symbol() is enough, no "kernel" needed.

Hi Huacai,

Using is_ignored_kernel_symbol() was suggested by Petr [1] to maintain
consistency with the existing naming convention in tools/perf.

For me, either is_ignored_kernel_symbol() or is_ignored_symbol() is
fine. I will leave it to Petr to make the final call on this.
