  [libunwind] Remove unnecessary strcpy dependency (#72043)

libunwind uses a minimal set of necessary standard library functions,
basically just `memset` and `memcpy`. There is a single use of `strcpy`
to copy the bytes `"CLNGUNW"` into a `uint64_t` object. This is both an
arguably odd use of the `strcpy` function as well as it unnecessarily
widens the set of library functions that must be available to build
libunwind, which can be an obstacle in baremetal scenarios. This change
simply replaces this one `strcpy` with the more fundamental `memcpy`.
