Log:
Declare getopt() instead of including unistd.h

I previously added a #include <unistd.h> to fix an implicit-declaration
problem of getopt(). This benchmark however comes with its own version
of getopt. This somehow failed LTO builds (the code in getopt.c maybe having a
slightly different ABI then what you get when including unistd.h).

Don't include unistd.h anymore and use an "int getopt();" forward
declaration instead.
