[PATCH 1/2] Add error message check in qemuxml2argv tests

[Sebastian Mitterle]

When an error is expected, the error message will be checked.
This is expressed by creating an additional ".err" file containing
the expected error message.

It is added in order to make sure the expected errors
are not masked by other errors during test execution while
leveraging the existing framework.

In order to keep it simple, an input file cannot be reused
anymore to cover several expected error cases configured
in the test code. An input file can still be reused by creating
a test case specific symlink.

For consistency, the mock needs to report an error now, too,
as every failure must have an error; otherwise a test case will
fail.

Require LC_ALL=C explicitly to make sure error messages are not
localized for testing.

Lastly, remove trailing blank in error message for domain_addr.c
virDomainCCWAddressAssign, uncovered by this change.
