flag: fix TestExitCode on Plan 9

CL 221427 added TestExitCode. This test is failing
on Plan 9 because ExitCode is always equal to 1
on error since Plan 9 use error strings.

This change fixes TestExitCode by checking that
ExitCode is equal to 1 on error instead of the
specific value.

Fixes #38237.
