Subject: [build] Fix "'%s' directive argument is null" error

[build] Fix "'%s' directive argument is null" error

Use '%p' directive, and print handle's address if the address is null
and the handle doesn't have a name.  This fixes the following
compilation error:

  interface/efi/efi_debug.c:334:3: error: '%s' directive
  argument is null [-Werror=format-overflow=]
