shellcraft can't use break syscall

[disconnect3d]

It is not possible to use the (old and currently unimplemented) break syscall through pwn.shellcraft as break is a Python keyword and the module tries to define def break(...) function:

An example for amd64:

>>> 'break' in dir(pwn.shellcraft.amd64)
True
>>> pwn.shellcraft.amd64.break
  File "<stdin>", line 1
    pwn.shellcraft.amd64.break
                             ^
SyntaxError: invalid syntax

And arm:

>>> 'break' in dir(pwn.shellcraft.arm)
True
>>> pwn.shellcraft.arm.break
  File "<stdin>", line 1
    pwn.shellcraft.arm.break
                           ^
SyntaxError: invalid syntax

The real cause (described above) can be easily spotted when interacting with IPython interactive shell:

This was fixed in #1355 and released in 3.13.0.

Thanks! 👍
