vere: change lmdb mapsize for aarch64

Browse Source 
Adds aarch64 lines to pkg/urbit/configure and defines a new macro, U3_CPU_aarch64.

That macro is used in pkg/urbit/vere/disk.c to change the lmdb mapsize from 1TB to 60GB for aarch64 on linux.

Uses #if defined instead of  #ifdef in anticipation of aarch64 on macos being a thing before the end of the year.
