kobject: Replace strncpy with memcpy

gcc 8.1.0 complains:

lib/kobject.c:128:3: warning:
	'strncpy' output truncated before terminating nul copying as many
	bytes from a string as its length [-Wstringop-truncation]
lib/kobject.c: In function 'kobject_get_path':
lib/kobject.c:125:13: note: length computed here

Using strncpy() is indeed less than perfect since the length of data to
be copied has already been determined with strlen(). Replace strncpy()
with memcpy() to address the warning and optimize the code a little.
