support: Set errno before testing it.
In test-conainer we should set errno to 0 before calling strtol, and check after with TEST_COMPARE. In tst-support_capture_subprocess we should set errno to 0 before checking it after the call to strtol. Tested on x86_64. Reviewed-by: DJ Delorie <dj@redhat.com>
