    sim: add some stdlib.h includes
    
    When trying to compile GDB with --target=avr, with gcc 9.2.0, I am
    getting a bunch of:
    
        /home/simark/src/binutils-gdb/sim/avr/../common/nrun.c:94:7: error: implicit declaration of function ‘abort’ [-Werror=implicit-function-declaration]
           94 |       abort ();
              |       ^~~~~
        /home/simark/src/binutils-gdb/sim/avr/../common/nrun.c:94:7: error: incompatible implicit declaration of built-in function ‘abort’ [-Werror]
        /home/simark/src/binutils-gdb/sim/avr/../common/nrun.c:94:7: note: include ‘<stdlib.h>’ or provide a declaration of ‘abort’
    
    I did what the compiler told me and added the relevant includes in the
    problematic files.
