tools/bin/ut: accelerate building test binary

[tiancaiamao]

What problem does this PR solve?

Issue Number: close #31880
A subtask for #30822

Problem Summary:

Build the test binary one by one is painfully slow.

Before change:

6m39.360986586s

After change:

1m56.399393108s

What is changed and how it works?

go test --exec=xprog, the Go compile toolchain would call your xprog program passing the test binary path as the argument...

So you can do this trick, write you own xprog, and move the test binary to some place else, save it for later use.

Check List

Tests

• Unit test
• Integration test
• Manual test (add detailed scripts or steps below)

Now you can use go test --exec=xprog to build all test binaries at once.
