perf: Fix const qualifier warnings in libbpf.cHEADmaster

Fix compilation warnings when building perf with -Werror where const
qualifiers are discarded from pointers returned by strstr() and
strchr() functions in libbpf.c.

Both strstr() and strchr() return 'const char *' when given
'const char *' input parameters. The receiving variables must
preserve this const qualification to maintain const-correctness
and avoid compiler warnings.

Errors fixed:
  libbpf.c:8179:13: error: assignment discards 'const' qualifier
    from pointer target type [-Werror=discarded-qualifiers]
  libbpf.c:11967:35: error: assignment discards 'const' qualifier
    from pointer target type [-Werror=discarded-qualifiers]

This is a workaround for kernel 6.12.x. The issue is already fixed
upstream in kernel 6.13+ and can be removed when the kernel is updated.
