Current SH will get below warning at strncpy()

In general, strncpy() should behave like below.
char dest[10];
char *src = "12345";
strncpy(dest, src, 10);
// dest = {'1', '2', '3', '4', '5',
'\0','\0','\0','\0','\0'}
But, current SH strnpy() has 2 issues.
1st is it will access to out-of-memory (= src + 10).
2nd is it needs big fixup for it, and maintenance __asm__
code is difficult.
To solve these issues, this patch simply uses generic strncpy()
instead of architecture specific one.

There is no point in having __KERNEL__ ifdefs in headers not exported to
userspace.

This follows the sparc changes a439fe51a1.
Most of the moving about was done with Sam's directions at:

with subsequent hacking and fixups entirely my fault.
