db: simplify initialization of ring-buffer

Currently, `strncpy` is used to copy the SQL statement to the ring
buffer, passing the length of the source string, which leads gcc to
complain:

  ../../util/db.c:231:25: warning: `strncpy` specified bound depends on the length of the source argument

In fact, the ring buffer is sized to be a multiple of the size of the
SQL buffer, and the SQL is simply copied multiple times at increasing
offsets, so use `strcpy` instead.
