entry.c: convert strcpy to xsnprintf
This particular conversion is non-obvious, because nobody has passed our function the length of the destination buffer. However, the interface to checkout_entry specifies that the buffer must be at least TEMPORARY_FILENAME_LENGTH bytes long, so we can check that (meaning the existing code was not buggy, but merely worrisome to somebody reading it).
