Log Message:
Pull up following revision(s) (requested by rin in ticket #856):

        tests/lib/libc/gen/t_siginfo.c: revision 1.54
        tests/lib/libc/gen/t_siginfo.c: revision 1.55

t_siginfo:sigbus_adraln: Skip rather than expect_fail on x86

This is an architecture-defined behavior, not a failure.
t_siginfo:adraln: Brush up skip message for x86

Note that:
1. No data address is reported back for alignment check exception, as per
   Intel SDM (June 2024).
2. Kernel sets faulting PC to si_addr.
3. 2. is compliant to siginfo(2), at least:
   For SIGILL, SIGFPE, SIGBUS and SIGSEGV ... si_addr contains
   the address of the faulting instruction or data and ...
4. IEEE Std 1003.1-2024 does not require si_addr for SIGBUS. For SIGILL
   and SIGSEGV, e.g., it is required (SHALL) to store faulting PC and
   data address, respectively, on the other hand.
