Since the definition of 'struct perf_sample' has been moved to sample.h,
we need to include this header file to fix the build error as follows:

arch/riscv/util/unwind-libdw.c: In function 'libdw__arch_set_initial_registers':
arch/riscv/util/unwind-libdw.c:12:50: error: invalid use of undefined type 'struct perf_sample'
   12 |         struct regs_dump *user_regs = &ui->sample->user_regs;
      |                                                  ^~
