sim: punt x86-specific bswap logic
The compiler/C library should produce reasonable code for htonl/ntohl,
and at least glibc tries pretty hard to always produce good code for
them. This logic only had support for 32-bit x86 systems anymore, and
it's unlikely people were even opting into this, so drop it all.
