[PATCH, applied] test-read-common: Fix error message

[Dodji Seketeli]

Hello,

The error message in test_task::run_abidw in test-read-common.cc is
wrong.  Fixed thus.  Also, emit the error message directly to the standard
error as the error is detected.

	* tests/test-read-common.cc (test_task::run_abidw): Fix error
	message and emit it to stderr directly.

Signed-off-by: Dodji Seketeli <dodji@redhat.com>
Applied to master branch.
