scripts/recordmcount.pl: Fix RISC-V regex for clang
Clang can generate R_RISCV_CALL_PLT relocations to _mcount:
$ llvm-objdump -dr build/riscv/init/main.o | rg mcount
000000000000000e: R_RISCV_CALL_PLT _mcount
000000000000004e: R_RISCV_CALL_PLT _mcount
After this, the __start_mcount_loc section is properly generated and
function tracing still works.
