Squashfs: remove deprecated strncpy by not copying the string

Squashfs copied the passed string (name) into a temporary buffer to ensure
it was NUL-terminated.  This however is completely unnecessary as the
string is already NUL-terminated.  So remove the deprecated strncpy() by
completely removing the string copy.

The background behind this unnecessary string copy is that it dates back
to the days when Squashfs was an out of kernel patch.  The code
deliberately did not assume the string was NUL-terminated in case in
future this changed (due to kernel changes).  This would mean the out of
tree patches would be broken but still compile OK.
