Occlum-compatible executable binaries must be Position-Independent Executable (PIE). Previously, to build such binaries, the users need to explicitly give `-buildmode=pie` flag to `occlum-go`. Apparently, this is error-prone. This commit sets `-buildmode=pie` by default for `occlum-go`. In addition, this commit upgrades the Go version to 1.13.7.
