[PATCH 1/3] binfmt_elf: Clean up the variable name of map flags

[Baoquan He]

In load_elf_interp() and elf_map(), variables with value of map flags
are named as type or elf_type. That may bring confusion since their
values not only contain map type which is MAP_SHARED or MAP_PRIVATE,
also MAP_FIXED or MAP_DENYWRITE, etc.

So change them as flags or elf_flags.
