Remove dependency to stdbool.h

While this header is standard in C99, it does not exist in C89/C90.
Microsoft Visual Studio added this header only in version 2013.
Still common common compilers Visual Studio 2010 and 2012 (and all earlier)
do not support it.

Here we do not really have a benefit as compared to just using 'int'
instead of 'bool', so this dependency can easily be avoided to support
Visual Studio 2010 (see also https://github.com/libcheck/check/issues/125).
