package/mpd: depends on gcc and host gcc >= 7
mpd uses string_view since version 0.22 and
https://github.com/MusicPlayerDaemon/MPD/commit/
fa45a8adfa44f6bc815ae7428770112c15c76d73
string_view is a C++17 feature:
https://github.com/MusicPlayerDaemon/MPD/commit/
e0e5ed62ee98a0e21bc928f432a0051854193cd2
So add a dependency on host gcc >= 7
Moreover, C++17 is also mandatory on the target side since
https://github.com/MusicPlayerDaemon/MPD/commit/
8f981845dc7376824d94fd24924788c582942929
so also bump the gcc dependency
Finally, drop BR2_TOOLCHAIN_HAS_GCC_BUG_64735 which is not needed as it
will always be true with gcc >= 7
