rtl8187: Fix warning generated when strncpy() destination length matches the sixe argument

[ Upstream commit 199ba9faca909e77ac533449ecd1248123ce89e7 ]

In gcc8, when the 3rd argument (size) of a call to strncpy() matches the
length of the first argument, the compiler warns of the possibility of an
unterminated string. Using strlcpy() forces a null at the end.
