LOG: [libc][wait] hard code __W_CONTINUED for SYS_waitid fallback (#125929)

riscv32 currently doesn't have SYS_wait4, so wait4 is implemented via fallback
to SYS_waitid. In #125572, I missed that we had one use of the removed
__W_CONTINUED value. Hard code it here.

Fixes: #125572

Added: 
    

Modified: 
    libc/src/sys/wait/wait4Impl.h

Removed:
