zdump: since we create ELF version 1 files use this value explicitly
...
The value of `EV_CURRENT` might change. The ELF specification says: "The value
of EV_CURRENT, though given as 1 above, will change as necessary to reflect the
current version number." [1]

zdump: dfi_elf: refactor nt_* functions
...
The functions are refactored so the `struct zg_fh` value is now passed as
argument to the `nt_*` functions instead of accessing the global variable `g.fh`
from within of the functions. This makes the functions reusable and easier to
test. While at it, improve the documentation of `nt_read`.

The primary goal of this change is to split DFO ELF module into
multiple smaller ones for better unit testability.
The change doesn't introduce any functionality changes, just shuffling code
around.
