[PATCH] libosmocore[master]: doc: clarify osmo_strlcpy() doc

doc: clarify osmo_strlcpy() doc

Stating that it 'truncates src' is misleading. Also clarify whether siz
includes the space needed for the terminating NUL.

- *  Copies up to \a siz characters from \a src to \a dst, but ensures

- *  truncate \a src to do achieve this.
+ * Copy at most \a siz bytes from \a src to \a dst, ensuring that the result is
+ * NUL terminated. The NUL character is included in \a siz, i.e. passing the
+ * actual sizeof(*dst) is correct.
