kern: fix mig_strncpy

Previously, the function mig_strncpy would always zero-terminate the
destination string.  Make mig_strncpy behave like mig_strncpy and
strncpy in the glibc.  Also fix the implementation of mig_strncpy to
return the length of the written string to align the implementation
with the declaration in include/mach/mig_support.h.

* kern/ipc_mig.c (mig_strncpy): Do not zero-terminate the destination
string.  Return length of destination string.
