Subject: tools/nolibc: make sys_mmap() automatically use the right __NR_mmap definition

tools/nolibc: make sys_mmap() automatically use the right __NR_mmap definition

__NR_mmap2 was used for i386 but it's also needed for other archs such
as RISCV32 or ARM. Let's decide to use it based on the __NR_mmap2
definition as it's not defined on other archs.
