Fix sys_mmap_metal() for non-MAP_FIXED case ()
- correctly check that virtual region we want to use is
  unmapped, rather than accidentally clobbering existing pages
- avoid placing mmap'd memory at null virtual address

Don't relocate file descriptor memory
This change fixes  where ASAN spotted a race condition that could
happen in multithreaded programs, with more than OPEN_MAX descriptors
when using ZipOS or Windows NT, which require tracking open file info
and this change fixes that table so it never relocates, thus allowing
us to continue to enjoy the benefits of avoiding locks while reading.
