package/supertux: needs gcc >= 6

The initial build issue [1] has been fixed upstream but the supertux
fail to link with boost libraries when using gcc 5 (which use C++11 by default):

libsupertux2_lib.a(main.cpp.o): In function `boost::system::error_category::std_category::equivalent(std::error_code const&, int) const':
main.cpp:(.text._ZNK5boost6system14error_category12std_category10equivalentERKSt10error_codei[_ZNK5boost6system14error_category12std_category10equivalentERKSt10error_codei]+0x32): undefined reference to `boost::system::detail::generic_category_instance'

collect2: error: ld returned 1 exit status

This is a similar issue as the one reported by [2].

With gcc 5, boost libraries are compiled using C++11 but
supertux2_lib.a is using C++14 standard.

To fix the issue, boost libraries should be build using C++14
standard but we currently don't have an option to "force" the
default C++ standard used by the compiler.

So bump the minimum gcc version to gcc 6 since the C++14 is
used by default.
