libvduse: Replace strcpy() with strncpy()
Coverity reported a string overflow issue since we copied "name" to "dev_config->name" without checking the length. This should be a false positive since we already checked the length of "name" in vduse_name_is_invalid(). But anyway, let's replace strcpy() with strncpy() (as a general library, we'd like to minimize dependencies on other libraries, so we didn't use g_strlcpy() here) to fix the coverity complaint.
