fix set hostname
Previously, when we set hostname: $ strace hostname abc ... sethostname("abc", 3) = -1 ENAMETOOLONG (File name too long) ... According to man 2 sethostname: "The len argument specifies the number of bytes in name. (Thus, name does not require a terminating null byte.)" We wrongly use the CopyStringIn() to check terminating zero byte in the implementation of sethostname syscall. To fix this, we use CopyInBytes() instead.
