this implements os.nice (which linked to a unix system call, changing process priority) function.

with this commit, rustpyhton works as below.

>>>>> import os
>>>>> os.nice(0)
0
>>>>> os.nice(-1)
-1
>>>>> os.nice(-10)
-11
>>>>> os.nice(10)
-1
>>>>> os.nice(20)
19
>>>>> os.nice(20)
19
>>>>> os.nice(-20)
-1
>>>>> os.nice(-12)
-13
>>>>> os.nice(-100)
-20

nice function is defined in posix module rather than os itself. Please move this funciton to posix module in the same file. (Search for mod posix {)
Then os module will import it from posix automatically. Becasue posix module is defined only for unix, you don't need to add #[cfg(unix)] then.
