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.
Fixes: #861
