prog: reduce the "uber-mmap" size
During minimization we create a single memory mapping that contains all the smaller mmap() ranges, so that other mmap() calls can be dropped. This "uber-mmap" used to start at 0x7f0000000000 regardless of where the smaller mappings were located. Change its starting address to the beginning of the first small mmap() range.
