Use quote include instead of angled include for sqlite3-binding.h

[yihanzhen]

I'm trying to depend on this library using bazel. After upgrading to macOS Catalina I keep seeing the error:

/private/var/tmp/_bazel_i/292155d2803b74186baeb737a4c74ee8/sandbox/darwin-sandbox/550/execroot/project/external/com_github_mattn_go_sqlite3/backup.go:10:10: error: 'sqlite3-binding.h' file not found with <angled> include; use "quotes" instead
#include <sqlite3-binding.h>
         ^~~~~~~~~~~~~~~~~~~
         "sqlite3-binding.h

Hopefully this PR would fix the issue for using this library with bazel while not affecting any other use cases.

The CI on macOS failed at setting up dependencies before running Go tests. And chance to rerun them?

[mattn]

Could you please rebase from master branch?

[yihanzhen]

Done!
