LoongArch: BPF: Adjust the jump offset of tail calls
Call the next bpf prog and skip the first instruction of TCC
initialization.
A total of 7 instructions are skipped:
'move t0, ra' 1 inst
'move_imm + jirl' 5 inst
'addid REG_TCC, zero, 0' 1 inst
Relevant test cases: the tailcalls test item in selftests/bpf.
