package/mpd: needs gcc >= 8

Since bump to version 0.22.3 in commit b6576a458ca0 (package/mpd: bump
to version 0.22.3), mpd needs gcc >= 8, as documented in their manual
[0], to avoid the following build failure with gcc 7.3.1:

/tmp/instance-7/output-1/host/opt/ext-toolchain/aarch64-linux-gnu/include/c++/7.3.1/bits/stl_tree.h:2091:28: error: no matching function for call to 'std::_Rb_tree<std::__cxx11::basic_string<char>, std::pair<const std::__cxx11::basic_string<char>, std::__cxx11::basic_string<char> >, std::_Select1st<std::pair<const std::__cxx11::basic_string<char>, std::__cxx11::basic_string<char> > >, std::less<std::__cxx11::basic_string<char> >, std::allocator<std::pair<const std::__cxx11::basic_string<char>, std::__cxx11::basic_string<char> > > >::_M_get_insert_unique_pos(std::pair<std::basic_string_view<char>, std::basic_string_view<char> >::first_type&)'
