[PATCH] staging: rtl8188eu: use strlcpy instead of strncpy

[Michael Straube]

Use strlcpy instead of strncpy to avoid gcc 8 warning:
warning: '__builtin_strncpy' specified bound 16 equals destination size [-Wstringop-truncation]

The maximum length of the source string including terminating null is 5.
Hence it always fits in the destination buffer of length 16.
