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.
Fixes: Coverity CID 1490224
