yjit_codegen.c: Prevent a possible out-of-bound access
The code attempts to read `C_ARG_REGS[leaf_builtin->argc + 1]`, and the
size of `C_ARG_REGS` is `NUM_C_ARG_REGS`. So, the guard condition must
be `leaf_builtin->argc + 1 + 1 <= NUM_C_ARG_REGS`.
This change fixes the off-by-one error. This issue was found by Coverity
Scan.
