Hubert Tong 66a9642f56 [lit][tests][AIX] Update expected form of diagnostic messages; use `not` to normalize non-zero exit values ... Summary: Various tests in the `lit` testing suite expect specific return codes and forms of diagnostic message from utility programs. As per POSIX.1-2017 XCU Section 1.4, Utility Description Defaults, "[the] format of diagnostic messages for most utilities is unspecified". The STDERR subsections of the `cat` and `wc` utilities merely indicate that "[the] standard error shall be used only for diagnostic messages". The corresponding EXIT STATUS subsections merely indicate, with regard to errors, an exit value of >0. The affected tests are updated to accept the applicable diagnostic message as produced by the utilities on AIX. The exit value is normalized using `not` as necessary.
