TestScript ignores exit codes

[Pavel Roskin]

Hello!

"make check" doesn't detect that some tests return 1 on exit. The code in 
test/regression/TestScript doesn't work as it should (tested on LinuxPCC,
bash-2.03).

My modified version uses a much more robust way to detect non-zero exit
codes. Creating an additional file doesn't seem to slow down the tests.

It is a good idea to retest TestNative on all platforms after applying
this patch, since its errors were silently ignored.

ChangeLog:
	test/regression/TestScript.in (run): fixed exit code analyzis
