bazel/sqlite3: link mattn/go-sqlite3 against the shared libsqlite3

Stop compiling the bundled SQLite amalgamation that ships with
github.com/mattn/go-sqlite3 and link the binding against //deps:sqlite3
instead. Removes one full SQLite C compile from every build, keeps a single
.so in the runtime artifacts (already shared by cpython, rpm, openscap).

- .bazelrc: enable the libsqlite3 Go build tag globally so
  sqlite3_libsqlite3.go compiles and defines USE_LIBSQLITE3, which makes
  the bundled sqlite3-binding.c a no-op TU and switches the cgo preamble
  to #include <sqlite3.h>.

- deps/go.MODULE.bazel: add a gazelle_override on github.com/mattn/go-sqlite3
  that (a) passes -build_tags=libsqlite3 so Gazelle picks the right sources
  in srcs, and (b) maps go_library to the go_sqlite3_library wrapper added
  in the previous commit, which injects cgo = True and the libsqlite3_dynamic
  cdep so #include <sqlite3.h> and -lsqlite3 resolve against //deps:sqlite3.

Verified by building //pkg/security/resolvers/sbom/collectorv2:collectorv2_test
and confirming via ldd that the binary dynamically links against the
@sqlite3//:sqlite3 shared library (single agent-owned libsqlite3.so) and
go-sqlite3's GoCompilePkg runs in ~0s (no amalgamation recompile).
