Use c_string to define host_get_kernel_version and host_get_kernel_boot_info.
The existing definitions for kernel_version_t and kernel_boot_info_t use
(MACH_MSG_TYPE_STRING, length*8) which result in message types that have
a single element of 512 or 4096 bytes (set as msgt_size). This results
in MiG generating mach_msg_type_long_t. Using c_string has the benefit
of moving this size to be defined as msgt_number which doesn't overflow.
This will allow us to simplify the 64 bit RPC ABI since all msgt_size can
be defined with just 8 bits (as it should be expected).
The resulting implementation is the same but we still need to define new
RPCs since server and user expect different mach_msg_type_t.
