iw: add support for retrieving keys

For debugging purposes, it can be useful to be able to retrieve keys.

Add a "iw key get" command, to be able to retrieve keys when the key
index is known. A new "key" section is also introduced, in preparation
for future key-related commands.

Example retrieving a pairwise key:
iw dev wlan0 key get 0 02:02:03:04:05:06

Example retrieving a group key:
iw dev wlan0 key get 1

Note that only the outer ATTR_KEY_DATA (and seq) is reported, the
nested KEY_DATA (and seq) within ATTR_KEY is not.

iw: Fix timestamp output on 32-bit architectures

On 32-bit architectures, time_t is 32-bit which causes overflows in the
arithmetic involving tv_sec, leading to invalid output. Fix this by
explicitly adding ULL suffixes to the constants used in those calculations.
