<5ms blk_ms is required by real world applications; see emulators/mednafen.

I would prefer if blk_ms were kept below 5ms on amd64 and aarch64.
We don't have to worry about the CPU load of playing audio on these platforms.
We also released 9 with blk_ms=4 on these platforms and nobody complained.

It's not a good idea to punish the majority of NetBSD users because m68k
is incredibly slow.
