[v3] make abicompat test happy

  When testing with runtestabicompat, the following problems were found:
1. abicompat tested multiple scenarios, but the last result was used
as the basis for the return value of the command.
2. For multiple test scenarios, the execution results cannot be known
after the test, which is easy to cause confusion.
3. The runtestabicompat command itself is executed successfully, so it
should return 0, which should be distinguished from the test result.

                * test/test-abicompat.cc (main): make test happy.

Actually, we want to return a non-zero value when any of the individual
tests fail.  This is because "make check" runs all the tests of the
regression test suite and it looks at the return value of each of the
runtestXXXX programs to detect if it failed or not.  So we really need
to be non-zero when a test case fails.

I fixed it and applied the patch below.  Thanks!

Cheers,
