[PATCH] sprint_symbol: Replace strcpy with memmove to handle potential overlap

[liujinlong]

In the function __sprint_symbol, replace strcpy with memmove to ensure
correct behavior even if the source and destination buffers overlap.
This change prevents potential undefined behavior flagged by recent
compilers as [-Werror=restrict].
