Li GuanandArnaldo Carvalho de Melo 7378b6656a perf riscv: Fix discarded const qualifier in _get_field() ...

The assignment of strrchr() return values to non-const char * variables
triggers a -Werror=discarded-qualifiers warning when building with GCC
14.

This happens because in newer glibc versions, strrchr() returns a 'const
char *' if the input string is const.

Properly declare 'line2' and 'nl' as const char * to match the glibc
function signature and ensure type safety. This avoids the need for
explicit type casting and aligns with the design pattern of not
modifying read-only memory in the perf tool.
