runtime: enable memory sanitizer on arm64
Changes include:
1. open compilation option -msan for arm64
2. modify doc to explain -msan is also supported on linux/arm64
3. wrap msan lib API in msan_arm64.s
4. use libc for sigaction syscalls when cgo is enabled
5. use libc for mmap syscalls when cgo is enabled
