libbpf: Fix riscv register names

Browse Source 
riscv registers are accessed via struct user_regs_struct, not struct
pt_regs. The program counter member in this struct is called pc, not
epc. The frame pointer is called s0, not fp.

Fixes: 3cc31d794097 ("libbpf: Normalize PT_REGS_xxx() macro definitions")
