When compiling SQLite, set the SQLITE_DEFAULT_MEMSTATUS=0 compile-time option.

This is the recommended option that is not enabled by default. Setting it to
zero avoids using a mutex (and thus suffering a performance penalty) during
every sqlite3_malloc() call, where this mutex is used to properly update the
allocations stats.  We don't use sqlite3_status(), so set this option to zero.

See https://sqlite.org/compile.html#recommended_compile_time_options

* subversion/libsvn_subr/sqlite3wrapper.c
  (): Define SQLITE_DEFAULT_MEMSTATUS=0.
