85501d8993 Improve implementation for occlum build 
This commit mainly accomplish two things:
1. Use makefile to manage dependencies for `occlum build`, which can save lots of time
2. Take dirs `build`, `run` outside from `.occlum`. Remove env var "OCCLUM_INSTANCE_DIR"

5e8f997d4d Make PIE the default mode for Go toolchain 
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.
